* [SPARK-6152] Use shaded ASM5 to support closure cleaning of Java 8 compiled ↵Josh Rosen2015-11-111-0/+4
| | | | | | | | | | | | | | | | classes This patch modifies Spark's closure cleaner (and a few other places) to use ASM 5, which is necessary in order to support cleaning of closures that were compiled by Java 8. In order to avoid ASM dependency conflicts, Spark excludes ASM from all of its dependencies and uses a shaded version of ASM 4 that comes from `reflectasm` (see [SPARK-782](https://issues.apache.org/jira/browse/SPARK-782) and #232). This patch updates Spark to use a shaded version of ASM 5.0.4 that was published by the Apache XBean project; the POM used to create the shaded artifact can be found at https://github.com/apache/geronimo-xbean/blob/xbean-4.4/xbean-asm5-shaded/pom.xml. http://movingfulcrum.tumblr.com/post/80826553604/asm-framework-50-the-missing-migration-guide was a useful resource while upgrading the code to use the new ASM5 opcodes. I also added a new regression tests in the `java8-tests` subproject; the existing tests were insufficient to catch this bug, which only affected Scala 2.11 user code which was compiled targeting Java 8.

* [SPARK-11236] [TEST-MAVEN] [TEST-HADOOP1.0] [CORE] Update Tachyon dependency ↵Calvin Jia2015-11-021-5/+1
| | | | | | | | | | | | 0.7.1 -> 0.8.1 This is a reopening of #9204 which failed hadoop1 sbt tests. With the original PR, a classpath issue would occur due to the MIMA plugin pulling in hadoop-2.2 dependencies regardless of the hadoop version when building the `oldDeps` project. These affect the hadoop1 sbt build because they are placed in `lib_managed` and Tachyon 0.8.0's default hadoop version is 2.2.

| | | | | | | | | | | | | | | This change does two things: - tag a few tests and adds the mechanism in the build to be able to disable those tags, both in maven and sbt, for both junit and scalatest suites. - add some logic to run-tests.py to disable some tags depending on what files have changed; that's used to disable expensive tests when a module hasn't explicitly been changed, to speed up testing for changes that don't directly affect those modules.

* [SPARK-7078] [SPARK-7079] Binary processing sort for Spark SQLJosh Rosen2015-07-101-10/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a cache-friendly external sorter which operates on serialized bytes and uses this sorter to implement a new sort operator for Spark SQL and DataFrames. ### Overview of the new sorter The new sorter design is inspired by [Alphasort](http://research.microsoft.com/pubs/68249/alphasort.doc) and implements a key-prefix optimization in order to improve the cache friendliness of the sort. In naive sort implementations, the sorting algorithm operates on an array of record pointers. To compare two records for ordering, the sorter must dereference these pointers, which likely involves random memory access, then compare the objects themselves. ![image](https://cloud.githubusercontent.com/assets/50748/8611390/3b1402ae-2675-11e5-8308-1a10bf347e6e.png) In a key-prefix sort, the sort operates on an array which stores the record pointer alongside a prefix of the record's key. When comparing two records for ordering, the sorter first compares the the stored key prefixes. If the ordering can be determined from the key prefixes (i.e. the prefixes are unequal), then the sort can avoid directly comparing the records, avoiding random memory accesses and full record comparisons. For example, if we're sorting a list of strings then we can store the first 8 bytes of the UTF-8 encoded string as the key-prefix and can perform unsigned byte-at-a-time comparisons to determine the ordering of strings based on their prefixes, only resorting to full comparisons for strings that share a common prefix. In cases where the sort key can fit entirely in the space allotted for the key prefix (e.g. the sorting key is an integer), we completely avoid direct record comparison. In this patch's implementation of key-prefix sorting, our sorter's internal array stores a 64-bit long and 64-bit pointer for each record being sorted. The key prefixes are generated by the user when inserting records into the sorter, which uses a user-defined comparison function for comparing them. The `PrefixComparators` object implements a set of comparators for many common types, including primitive numeric types and UTF-8 strings. The actual sorting is implemented by `UnsafeInMemorySorter`. Most consumers will not use this directly, but instead will use `UnsafeExternalSorter`, a class which implements a sort that can spill to disk in response to memory pressure. Internally, `UnsafeExternalSorter` creates `UnsafeInMemorySorters` to perform sorting and uses `UnsafeSortSpillReader/Writer` to spill and read back runs of sorted records and `UnsafeSortSpillMerger` to merge multiple sorted spills into a single sorted iterator. This external sorter integrates with Spark's existing ShuffleMemoryManager for controlling spilling. Many parts of this sorter's design are based on / copied from the more specialized external sort implementation that I designed for the new UnsafeShuffleManager write path; see #5868 for more details on that patch. ### Sorting rows in Spark SQL For now, `UnsafeExternalSorter` is only used by Spark SQL, which uses it to implement a new sort operator, `UnsafeExternalSort`. This sort operator uses a SQL-specific class called `UnsafeExternalRowSorter` that configures an `UnsafeExternalSorter` to use prefix generators and comparators that operate on rows encoded in the UnsafeRow format that was designed for Project Tungsten. I used some interesting unit-testing techniques to test this patch's SQL-specific components. `UnsafeExternalSortSuite` uses the SQL random data generators introduced in #7176 to test the UnsafeSort operator with all atomic types both with and without nullability and in both ascending and descending sort orders. `PrefixComparatorsSuite` contains a cool use of ScalaCheck + ScalaTest's `GeneratorDrivenPropertyChecks` in order to test UTF8String prefix comparison. ### Misc. additional improvements made in this patch This patch made several miscellaneous improvements to related code in Spark SQL: - The logic for selecting physical sort operator implementations, which was partially duplicated in both `Exchange` and `SparkStrategies, has now been consolidated into a `getSortOperator()` helper function in `SparkStrategies`. - The `SparkPlanTest` unit testing helper trait has been extended with new methods for comparing the output produced by two different physical plans. This makes it easy to write tests which assert that two physical operator implementations should produce the same output. I also added a method for disabling the implicit sorting of outputs prior to comparing them, a change which is necessary in order to be able to write proper SparkPlan tests for sort operators. ### Tasks deferred to followup patches While most of this patch's features are reasonably well-tested and complete, there are a number of tasks that are intentionally being deferred to followup patches: - Add tests which mock the ShuffleMemoryManager to check that memory pressure properly triggers spilling (there are examples of this type of test in #5868). - Add tests to ensure that spill files are properly cleaned up after errors. I'd like to do this in the context of a patch which introduces more general metrics for ensuring proper cleanup of tasks' temporary files; see https://issues.apache.org/jira/browse/SPARK-8966 for more details. - Metrics integration: there are some open questions regarding how to track / report spill metrics for non-shuffle operations, so I've deferred most of the IO / shuffle metrics integration for now. - Performance profiling. <!-- Reviewable:start --> [<img src="https://reviewable.io/review_button.png" height=40 alt="Review on Reviewable"/>](https://reviewable.io/reviews/apache/spark/6444) <!-- Reviewable:end --> Author: Josh Rosen <joshrosen@databricks.com> Closes #6444 from JoshRosen/sql-external-sort and squashes the following commits: 6beb467 [Josh Rosen] Remove a bunch of overloaded methods to avoid default args. issue 2bbac9c [Josh Rosen] Merge remote-tracking branch 'origin/master' into sql-external-sort 35dad9f [Josh Rosen] Make sortAnswers = false the default in SparkPlanTest 5135200 [Josh Rosen] Fix spill reading for large rows;

* [SPARK-7081] Faster sort-based shuffle path using binary processing ↵Josh Rosen2015-05-131-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | cache-aware sort This patch introduces a new shuffle manager that enhances the existing sort-based shuffle with a new cache-friendly sort algorithm that operates directly on binary data. The goals of this patch are to lower memory usage and Java object overheads during shuffle and to speed up sorting. It also lays groundwork for follow-up patches that will enable end-to-end processing of serialized records. The new shuffle manager, `UnsafeShuffleManager`, can be enabled by setting `spark.shuffle.manager=tungsten-sort` in SparkConf. The new shuffle manager uses directly-managed memory to implement several performance optimizations for certain types of shuffles. In cases where the new performance optimizations cannot be applied, the new shuffle manager delegates to SortShuffleManager to handle those shuffles. UnsafeShuffleManager's optimizations will apply when _all_ of the following conditions hold: - The shuffle dependency specifies no aggregation or output ordering. - The shuffle serializer supports relocation of serialized values (this is currently supported by KryoSerializer and Spark SQL's custom serializers). - The shuffle produces fewer than 16777216 output partitions. - No individual record is larger than 128 MB when serialized. In addition, extra spill-merging optimizations are automatically applied when the shuffle compression codec supports concatenation of serialized streams. This is currently supported by Spark's LZF serializer. At a high-level, UnsafeShuffleManager's design is similar to Spark's existing SortShuffleManager. In sort-based shuffle, incoming records are sorted according to their target partition ids, then written to a single map output file. Reducers fetch contiguous regions of this file in order to read their portion of the map output. In cases where the map output data is too large to fit in memory, sorted subsets of the output can are spilled to disk and those on-disk files are merged to produce the final output file. UnsafeShuffleManager optimizes this process in several ways: - Its sort operates on serialized binary data rather than Java objects, which reduces memory consumption and GC overheads. This optimization requires the record serializer to have certain properties to allow serialized records to be re-ordered without requiring deserialization. See SPARK-4550, where this optimization was first proposed and implemented, for more details. - It uses a specialized cache-efficient sorter (UnsafeShuffleExternalSorter) that sorts arrays of compressed record pointers and partition ids. By using only 8 bytes of space per record in the sorting array, this fits more of the array into cache. - The spill merging procedure operates on blocks of serialized records that belong to the same partition and does not need to deserialize records during the merge. - When the spill compression codec supports concatenation of compressed data, the spill merge simply concatenates the serialized and compressed spill partitions to produce the final output partition. This allows efficient data copying methods, like NIO's `transferTo`, to be used and avoids the need to allocate decompression or copying buffers during the merge. The shuffle read path is unchanged. This patch is similar to [SPARK-4550](http://issues.apache.org/jira/browse/SPARK-4550) / #4450 but uses a slightly different implementation. The `unsafe`-based implementation featured in this patch lays the groundwork for followup patches that will enable sorting to operate on serialized data pages that will be prepared by Spark SQL's new `unsafe` operators (such as the new aggregation operator introduced in #5725). ### Future work There are several tasks that build upon this patch, which will be left to future work: - [SPARK-7271](https://issues.apache.org/jira/browse/SPARK-7271) Redesign / extend the shuffle interfaces to accept binary data as input. The goal here is to let us bypass serialization steps in cases where the sort input is produced by an operator that operates directly on binary data. - Extension / redesign of the `Serializer` API. We can add new methods which allow serializers to determine the size requirements for serializing objects and for serializing objects directly to a specified memory address (similar to how `UnsafeRowConverter` works in Spark SQL). <!-- Reviewable:start --> [<img src="https://reviewable.io/review_button.png" height=40 alt="Review on Reviewable"/>](https://reviewable.io/reviews/apache/spark/5868) <!-- Reviewable:end --> Author: Josh Rosen <joshrosen@databricks.com> Closes #5868 from JoshRosen/unsafe-sort and squashes the following commits: ef0a86e [Josh Rosen] Fix scalastyle errors 7610f2f [Josh Rosen] Add tests for proper cleanup of shuffle data. d494ffe [Josh Rosen] Fix deserialization of JavaSerializer instances. 52a9981 [Josh Rosen] Fix some bugs in the address packing code. 51812a7 [Josh Rosen] Change shuffle manager sort name to tungsten-sort 4023fa4 [Josh Rosen] Add @Private annotation to some Java classes. de40b9d [Josh Rosen] More comments to try to explain metrics code df07699 [Josh Rosen] Attempt to clarify confusing metrics update code 5e189c6 [Josh Rosen] Track time spend closing / flushing files; split TimeTrackingOutputStream into separate file. d5779c6 [Josh Rosen] Merge remote-tracking branch 'origin/master' into unsafe-sort c2ce78e [Josh Rosen] Fix a missed usage of MAX_PARTITION_ID e3b8855 [Josh Rosen] Cleanup in UnsafeShuffleWriter 4a2c785 [Josh Rosen] rename 'sort buffer' to 'pointer array' 6276168 [Josh Rosen] Remove ability to disable spilling in UnsafeShuffleExternalSorter. 57312c9 [Josh Rosen] Clarify fileBufferSize units 2d4e4f4 [Josh Rosen] Address some minor comments in UnsafeShuffleExternalSorter. fdcac08 [Josh Rosen] Guard against overflow when expanding sort buffer. 85da63f [Josh Rosen] Cleanup in UnsafeShuffleSorterIterator. 0ad34da [Josh Rosen] Fix off-by-one in nextInt() call 56781a1 [Josh Rosen] Rename UnsafeShuffleSorter to UnsafeShuffleInMemorySorter e995d1a [Josh Rosen] Introduce MAX_SHUFFLE_OUTPUT_PARTITIONS. e58a6b4 [Josh Rosen] Add more tests for PackedRecordPointer encoding. 4f0b770 [Josh Rosen] Attempt to implement proper shuffle write metrics. d4e6d89 [Josh Rosen] Update to bit shifting constants 69d5899 [Josh Rosen] Remove some unnecessary override vals 8531286 [Josh Rosen] Add tests that automatically trigger spills. 7c953f9 [Josh Rosen] Add test that covers UnsafeShuffleSortDataFormat.swap(). e1855e5 [Josh Rosen] Fix a handful of misc.

* [SPARK-7076][SPARK-7077][SPARK-7080][SQL] Use managed memory for aggregationsJosh Rosen2015-04-291-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds managed-memory-based aggregation to Spark SQL / DataFrames. Instead of working with Java objects, this new aggregation path uses `sun.misc.Unsafe` to manipulate raw memory. This reduces the memory footprint for aggregations, resulting in fewer spills, OutOfMemoryErrors, and garbage collection pauses. As a result, this allows for higher memory utilization. It can also result in better cache locality since objects will be stored closer together in memory. This feature can be eanbled by setting `spark.sql.unsafe.enabled=true`. For now, this feature is only supported when codegen is enabled and only supports aggregations for which the grouping columns are primitive numeric types or strings and aggregated values are numeric. ### Managing memory with sun.misc.Unsafe This patch supports both on- and off-heap managed memory. - In on-heap mode, memory addresses are identified by the combination of a base Object and an offset within that object. - In off-heap mode, memory is addressed directly with 64-bit long addresses. To support both modes, functions that manipulate memory accept both `baseObject` and `baseOffset` fields. In off-heap mode, we simply pass `null` as `baseObject`. We allocate memory in large chunks, so memory fragmentation and allocation speed are not significant bottlenecks. By default, we use on-heap mode. To enable off-heap mode, set `spark.unsafe.offHeap=true`. To track allocated memory, this patch extends `SparkEnv` with an `ExecutorMemoryManager` and supplies each `TaskContext` with a `TaskMemoryManager`. These classes work together to track allocations and detect memory leaks. ### Compact tuple format This patch introduces `UnsafeRow`, a compact row layout. In this format, each tuple has three parts: a null bit set, fixed length values, and variable-length values: ![image](https://cloud.githubusercontent.com/assets/50748/7328538/2fdb65ce-ea8b-11e4-9743-6c0f02bb7d1f.png) - Rows are always 8-byte word aligned (so their sizes will always be a multiple of 8 bytes) - The bit set is used for null tracking: - Position _i_ is set if and only if field _i_ is null - The bit set is aligned to an 8-byte word boundary. - Every field appears as an 8-byte word in the fixed-length values part: - If a field is null, we zero out the values. - If a field is variable-length, the word stores a relative offset (w.r.t. the base of the tuple) that points to the beginning of the field's data in the variable-length part. - Each variable-length data type can have its own encoding: - For strings, the first word stores the length of the string and is followed by UTF-8 encoded bytes. If necessary, the end of the string is padded with empty bytes in order to ensure word-alignment. For example, a tuple that consists 3 fields of type (int, string, string), with value (null, “data”, “bricks”) would look like this: ![image](https://cloud.githubusercontent.com/assets/50748/7328526/1e21959c-ea8b-11e4-9a28-a4350fe4a7b5.png) This format allows us to compare tuples for equality by directly comparing their raw bytes. This also enables fast hashing of tuples. ### Hash map for performing aggregations This patch introduces `UnsafeFixedWidthAggregationMap`, a hash map for performing aggregations where the aggregation result columns are fixed-with. This map's keys and values are `Row` objects. `UnsafeFixedWidthAggregationMap` is implemented on top of `BytesToBytesMap`, an append-only map which supports byte-array keys and values. `BytesToBytesMap` stores pointers to key and value tuples. For each record with a new key, we copy the key and create the aggregation value buffer for that key and put them in a buffer. The hash table then simply stores pointers to the key and value. For each record with an existing key, we simply run the aggregation function to update the values in place. This map is implemented using open hashing with triangular sequence probing. Each entry stores two words in a long array: the first word stores the address of the key and the second word stores the relative offset from the key tuple to the value tuple, as well as the key's 32-bit hashcode. By storing the full hashcode, we reduce the number of equality checks that need to be performed to handle position collisions ()since the chance of hashcode collision is much lower than position collision). `UnsafeFixedWidthAggregationMap` allows regular Spark SQL `Row` objects to be used when probing the map. Internally, it encodes these rows into `UnsafeRow` format using `UnsafeRowConverter`. This conversion has a small overhead that can be eliminated in the future once we use UnsafeRows in other operators. <!-- Reviewable:start --> [<img src="https://reviewable.io/review_button.png" height=40 alt="Review on Reviewable"/>](https://reviewable.io/reviews/apache/spark/5725) <!-- Reviewable:end --> Author: Josh Rosen <joshrosen@databricks.com> Closes #5725 from JoshRosen/unsafe and squashes the following commits: eeee512 [Josh Rosen] Add converters for Null, Boolean, Byte, and Short columns. 81f34f8 [Josh Rosen] Follow 'place children last' convention for GeneratedAggregate 1bc36cc [Josh Rosen] Refactor UnsafeRowConverter to avoid unnecessary boxing. 017b2dc [Josh Rosen] Remove BytesToBytesMap.finalize() 50e9671 [Josh Rosen] Throw memory leak warning even in case of error; add warning about code duplication 70a39e4 [Josh Rosen] Split MemoryManager into ExecutorMemoryManager and TaskMemoryManager: 6e4b192 [Josh Rosen] Remove an unused method from ByteArrayMethods. de5e001 [Josh Rosen] Fix debug vs. trace in logging message. a19e066 [Josh Rosen] Rename unsafe Java test suites to match Scala test naming convention. 78a5b84 [Josh Rosen] Add logging to MemoryManager ce3c565 [Josh Rosen] More comments, formatting, and code cleanup. 529e571 [Josh Rosen] Measure timeSpentResizing in nanoseconds instead of milliseconds. 3ca84b2 [Josh Rosen] Only zero the used portion of groupingKeyConversionScratchSpace 162caf7 [Josh Rosen] Fix test compilation b45f070 [Josh Rosen] Don't redundantly store the offset from key to value, since we can compute this from the key size. a8e4a3f [Josh Rosen] Introduce MemoryManager interface; add to SparkEnv. 0925847 [Josh Rosen] Disable MiMa checks for new unsafe module cde4132 [Josh Rosen] Add missing pom.xml 9c19fc0 [Josh Rosen] Add configuration options for heap vs. offheap 6ffdaa1 [Josh Rosen] Null handling improvements in UnsafeRow. 31eaabc [Josh Rosen] Lots of TODO and doc cleanup. a95291e [Josh Rosen] Cleanups to string handling code afe8dca [Josh Rosen] Some Javadoc cleanup f3dcbfe [Josh Rosen] More mod replacement 854201a [Josh Rosen] Import and comment cleanup 06e929d [Josh Rosen] More warning cleanup ef6b3d3 [Josh Rosen] Fix a bunch of FindBugs and IntelliJ inspections 29a7575 [Josh Rosen] Remove debug logging 49aed30 [Josh Rosen] More long -> int conversion. b26f1d3 [Josh Rosen] Fix bug in murmur hash implementation. 765243d [Josh Rosen] Enable optional performance metrics for hash map. 23a440a [Josh Rosen] Bump up default hash map size 628f936 [Josh Rosen] Use ints intead of longs for indexing. 92d5a06 [Josh Rosen] Address a number of minor code review comments. 1f4b716 [Josh Rosen] Merge Unsafe code into the regular GeneratedAggregate, guarded by a configuration flag; integrate planner support and re-enable all tests. d85eeff [Josh Rosen] Add basic sanity test for UnsafeFixedWidthAggregationMap bade966 [Josh Rosen] Comment update (bumping to refresh GitHub cache...) b3eaccd [Josh Rosen] Extract aggregation map into its own class. d2bb986 [Josh Rosen] Update to implement new Row methods added upstream 58ac393 [Josh Rosen] Use UNSAFE allocator in GeneratedAggregate (TODO: make this configurable) 7df6008 [Josh Rosen] Optimizations related to zeroing out memory: c1b3813 [Josh Rosen] Fix bug in UnsafeMemoryAllocator.free(): 738fa33 [Josh Rosen] Add feature flag to guard UnsafeGeneratedAggregate c55bf66 [Josh Rosen] Free buffer once iterator has been fully consumed. 62ab054 [Josh Rosen] Optimize for fact that get() is only called on String columns. c7f0b56 [Josh Rosen] Reuse UnsafeRow pointer in UnsafeRowConverter ae39694 [Josh Rosen] Add finalizer as "cleanup method of last resort" c754ae1 [Josh Rosen] Now that the store*() contract has been stregthened, we can remove an extra lookup f764d13 [Josh Rosen] Simplify address + length calculation in Location. 079f1bf [Josh Rosen] Some clarification of the BytesToBytesMap.lookup() / set() contract. 1a483c5 [Josh Rosen] First version that passes some aggregation tests: fc4c3a8 [Josh Rosen] Sketch how the converters will be used in UnsafeGeneratedAggregate 53ba9b7 [Josh Rosen] Start prototyping Java Row -> UnsafeRow converters 1ff814d [Josh Rosen] Add reminder to free memory on iterator completion 8a8f9df [Josh Rosen] Add skeleton for GeneratedAggregate integration. 5d55cef [Josh Rosen] Add skeleton for Row implementation. f03e9c1 [Josh Rosen] Play around with Unsafe implementations of more string methods. ab68e08 [Josh Rosen] Begin merging the UTF8String implementations. 480a74a [Josh Rosen] Initial import of code from Databricks unsafe utils repo.

* [SPARK-6122] [CORE] Upgrade tachyon-client version to 0.6.3Calvin Jia2015-04-241-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a reopening of #4867. A short summary of the issues resolved from the previous PR: 1. HTTPClient version mismatch: Selenium (used for UI tests) requires version 4.3.x, and Tachyon included 4.2.5 through a transitive dependency of its shaded thrift jar. To address this, Tachyon 0.6.3 will promote the transitive dependencies of the shaded jar so they can be excluded in spark. 2. Jackson-Mapper-ASL version mismatch: In lower versions of hadoop-client (ie. 1.0.4), version 1.0.1 is included. The parquet library used in spark sql requires version 1.8+. Its unclear to me why upgrading tachyon-client would cause this dependency to break. The solution was to exclude jackson-mapper-asl from hadoop-client. It seems that the dependency management in spark-parent will not work on transitive dependencies, one way to make sure jackson-mapper-asl is included with the correct version is to add it as a top level dependency. The best solution would be to exclude the dependency in the modules which require a higher version, but that did not fix the unit tests. Any suggestions on the best way to solve this would be appreciated!

The SparkR package contains both RDD and DataFrame APIs in R and is integrated with Spark's submission scripts to work on different cluster managers. Some integration points that would be great to get feedback on: 1. Build procedure: SparkR requires R to be installed on the machine to be built. Right now we have a new Maven profile `-PsparkR` that can be used to enable SparkR builds 2. YARN cluster mode: The R package that is built needs to be present on the driver and all the worker nodes during execution. The R package location is currently set using SPARK_HOME, but this might not work on YARN cluster mode. The SparkR package represents the work of many contributors and attached below is a list of people along with areas they worked on edwardt (edwart) - Documentation improvements Felix Cheung (felixcheung) - Documentation improvements Hossein Falaki (falaki) - Documentation improvements Chris Freeman (cafreeman) - DataFrame API, Programming Guide Todd Gao (7c00) - R worker Internals Ryan Hafen (hafen) - SparkR Internals Qian Huang (hqzizania) - RDD API Hao Lin (hlin09) - RDD API, Closure cleaner Evert Lammerts (evertlammerts) - DataFrame API Davies Liu (davies) - DataFrame API, R worker internals, Merging with Spark Yi Lu (lythesia) - RDD API, Worker internals Matt Massie (massie) - Jenkins build Harihar Nahak (hnahak87) - SparkR examples Oscar Olmedo (oscaroboto) - Spark configuration Antonio Piccolboni (piccolbo) - SparkR examples, Namespace bug fixes Dan Putler (dputler) - Dataframe API, SparkR Install Guide Ashutosh Raina (ashutoshraina) - Build improvements Josh Rosen (joshrosen) - Travis CI build Sun Rui (sun-rui)- RDD API, JVM Backend, Shuffle improvements Shivaram Venkataraman (shivaram) - RDD API, JVM Backend, Worker Internals Zongheng Yang (concretevitamin) - RDD API, Pipelined RDDs, Examples and EC2 guide Author: Shivaram Venkataraman <shivaram@cs.berkeley.edu> Author: Shivaram Venkataraman <shivaram.venkataraman@gmail.com> Author: Zongheng Yang <zongheng.y@gmail.com> Author: cafreeman <cfreeman@alteryx.com> Author: Shivaram Venkataraman <shivaram@eecs.berkeley.edu> Author: Davies Liu <davies@databricks.com> Author: Davies Liu <davies.liu@gmail.com> Author: hlin09 <hlin09pu@gmail.com> Author: Sun Rui <rui.sun@intel.com> Author: lythesia <iranaikimi@gmail.com> Author: oscaroboto <oscarjr@gmail.com> Author: Antonio Piccolboni <antonio@piccolboni.info> Author: root <edward> Author: edwardt <edwardt.tril@gmail.com> Author: hqzizania <qian.huang@intel.com> Author: dputler <dan.putler@gmail.com> Author: Todd Gao <todd.gao.2013@gmail.com> Author: Chris Freeman <cfreeman@alteryx.com> Author: Felix Cheung <fcheung@AVVOMAC-119.local> Author: Hossein <hossein@databricks.com> Author: Evert Lammerts <evert@apache.org> Author: Felix Cheung <fcheung@avvomac-119.t-mobile.com> Author: felixcheung <felixcheung_m@hotmail.com> Author: Ryan Hafen <rhafen@gmail.com> Author: Ashutosh Raina <ashutoshraina@users.noreply.github.com> Author: Oscar Olmedo <oscarjr@gmail.com> Author: Josh Rosen <rosenville@gmail.com> Author: Yi Lu <iranaikimi@gmail.com> Author: Harihar Nahak <hnahak87@users.noreply.github.com> Closes #5096 from shivaram/R and squashes the following commits: da64742 [Davies Liu] fix Date serialization 59266d1 [Davies Liu] check exclusive of primary-py-file and primary-r-file 55808e4 [Davies Liu] fix tests 5581c75 [Davies Liu] update author of SparkR f731b48 [Shivaram Venkataraman] Only run SparkR tests if R is installed 64eda24 [Shivaram Venkataraman] Merge branch 'R' of https://github.com/amplab-extras/spark into R d7c3f22 [Shivaram Venkataraman] Address code review comments Changes include 1.

* [SPARK-4924] Add a library for launching Spark jobs programmatically.Marcelo Vanzin2015-03-111-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change encapsulates all the logic involved in launching a Spark job into a small Java library that can be easily embedded into other applications. The overall goal of this change is twofold, as described in the bug: - Provide a public API for launching Spark processes. This is a common request from users and currently there's no good answer for it. - Remove a lot of the duplicated code and other coupling that exists in the different parts of Spark that deal with launching processes. A lot of the duplication was due to different code needed to build an application's classpath (and the bootstrapper needed to run the driver in certain situations), and also different code needed to parse spark-submit command line options in different contexts. The change centralizes those as much as possible so that all code paths can rely on the library for handling those appropriately.

* [SPARK-5735] Replace uses of EasyMock with MockitoJosh Rosen2015-02-131-10/+0
| | | | | | | | | | | | | | | | | | | This patch replaces all uses of EasyMock with Mockito. There are two motivations for this: 1. We should use a single mocking framework in our tests in order to keep things consistent. 2. EasyMock may be responsible for non-deterministic unit test failures due to its Objensis dependency (see SPARK-5626 for more details). Most of these changes are fairly mechanical translations of Mockito code to EasyMock, although I made a small change that strengthens the assertions in one test in KinesisReceiverSuite.

* [SPARK-5388] Provide a stable application submission gateway for standalone ↵Andrew Or2015-02-061-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | cluster mode The goal is to provide a stable, REST-based application submission gateway that is not inherently based on Akka, which is unstable across versions. This PR targets standalone cluster mode, but is implemented in a general enough manner that can be potentially extended to other modes in the future. Client mode is currently not included in the changes here because there are many more Akka messages exchanged there. As of the changes here, the Master will advertise two ports, 7077 and 6066. We need to keep around the old one (7077) for client mode and older versions of Spark submit. However, all new versions of Spark submit will use the REST gateway (6066). By the way this includes ~700 lines of tests and ~200 lines of license.
