* [SPARK-2857] Correct properties to set Master / Worker portsAndrew Or2014-08-051-2/+2
| | | | | | | | | | | `master.ui.port` and `worker.ui.port` were never picked up by SparkConf, simply because they are not prefixed with "spark." Unfortunately, this is also currently the documented way of setting these values. Author: Andrew Or <andrewor14@gmail.com> Closes #1779 from andrewor14/master-worker-port and squashes the following commits: 8475e95 [Andrew Or] Update docs to reflect changes in configs 4db3d5d [Andrew Or] Stop using configs that don't actually work
* SPARK-2792. Fix reading too much or too little data from each stream in ↵Matei Zaharia2014-08-041-1/+1
| | | | | | | | | | | | | | | | | | | | ExternalMap / Sorter All these changes are from mridulm's work in #1609, but extracted here to fix this specific issue and make it easier to merge not 1.1. This particular set of changes is to make sure that we read exactly the right range of bytes from each spill file in EAOM: some serializers can write bytes after the last object (e.g. the TC_RESET flag in Java serialization) and that would confuse the previous code into reading it as part of the next batch. There are also improvements to cleanup to make sure files are closed. In addition to bringing in the changes to ExternalAppendOnlyMap, I also copied them to the corresponding code in ExternalSorter and updated its test suite to test for the same issues.

* [SPARK-2784][SQL] Deprecate hql() method in favor of a config option, ↵Michael Armbrust2014-08-031-9/+9
| | | | | | | | | | | | | | | | | | | | 'spark.sql.dialect' Many users have reported being confused by the distinction between the `sql` and `hql` methods. Specifically, many users think that `sql(...)` cannot be used to read hive tables. In this PR I introduce a new configuration option `spark.sql.dialect` that picks which dialect with be used for parsing. For SQLContext this must be set to `sql`. In `HiveContext` it defaults to `hiveql` but can also be set to `sql`. The `hql` and `hiveql` methods continue to act the same but are now marked as deprecated. **This is a possibly breaking change for some users unless they set the dialect manually, though this is unlikely.** For example: `hiveContex.sql("SELECT 1")` will now throw a parsing exception by default.

* [SPARK-2739][SQL] Rename registerAsTable to registerTempTableMichael Armbrust2014-08-021-9/+9
| | | | | | | | | | | | | There have been user complaints that the difference between `registerAsTable` and `saveAsTable` is too subtle. This PR addresses this by renaming `registerAsTable` to `registerTempTable`, which more clearly reflects what is happening. `registerAsTable` remains, but will cause a deprecation warning.

| | | | | | | | | | | | | | | | | | This is a sketch of a patch that allows the UI to show metrics for tasks that have not yet completed. It adds a heartbeat every 2 seconds from the executors to the driver, reporting metrics for all of the executor's tasks.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | JIRA issue: https://issues.apache.org/jira/browse/SPARK-2024 This PR is a followup to #455 and adds capabilities for saving PySpark RDDs using SequenceFile or any Hadoop OutputFormats. * Added RDD methods ```saveAsSequenceFile```, ```saveAsHadoopFile``` and ```saveAsHadoopDataset```, for both old and new MapReduce APIs. * Default converter for converting common data types to Writables. Users may specify custom converters to convert to desired data types. * No out-of-box support for reading/writing arrays, since ArrayWritable itself doesn't have a no-arg constructor for creating an empty instance upon reading. Users need to provide ArrayWritable subtypes. Custom converters for converting arrays to suitable ArrayWritable subtypes are also needed when writing. When reading, the default converter will convert any custom ArrayWritable subtypes to ```Object[]``` and they get pickled to Python tuples. * Added HBase and Cassandra output examples to show how custom output formats and converters can be used. cc MLnick mateiz ahirreddy pwendell Author: Kan Zhang <kzhang@apache.org> Closes #1338 from kanzhang/SPARK-2024 and squashes the following commits: c01e3ef [Kan Zhang] [SPARK-2024] code formatting 6591e37 [Kan Zhang] [SPARK-2024] renaming pickled -> pickledRDD d998ad6 [Kan Zhang] [SPARK-2024] refectoring to get method params below 10 57a7a5e [Kan Zhang] [SPARK-2024] correcting typo 75ca5bd [Kan Zhang] [SPARK-2024] Better type checking for batch serialized RDD 0bdec55 [Kan Zhang] [SPARK-2024] Refactoring newly added tests 9f39ff4 [Kan Zhang] [SPARK-2024] Adding 2 saveAsHadoopDataset tests 0c134f3 [Kan Zhang] [SPARK-2024] Test refactoring and adding couple unbatched cases 7a176df [Kan Zhang] [SPARK-2024] Add saveAsSequenceFile to PySpark

* [SPARK-2410][SQL] Merging Hive Thrift/JDBC server (with Maven profile fix)Cheng Lian2014-07-281-3/+198
| | | | | | | | | | | | | | | JIRA issue: [SPARK-2410](https://issues.apache.org/jira/browse/SPARK-2410) Another try for #1399 & #1600. Those two PR breaks Jenkins builds because we made a separate profile `hive-thriftserver` in sub-project `assembly`, but the `hive-thriftserver` module is defined outside the `hive-thriftserver` profile. Thus every time a pull request that doesn't touch SQL code will also execute test suites defined in `hive-thriftserver`, but tests fail because related .class files are not included in the assembly jar. In the most recent commit, module `hive-thriftserver` is moved into its own profile to fix this problem. All previous commits are squashed for clarity.

* [SPARK-1777] Prevent OOMs from single partitionsAndrew Or2014-07-271-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | **Problem.** When caching, we currently unroll the entire RDD partition before making sure we have enough free memory. This is a common cause for OOMs especially when (1) the BlockManager has little free space left in memory, and (2) the partition is large. **Solution.** We maintain a global memory pool of `M` bytes shared across all threads, similar to the way we currently manage memory for shuffle aggregation. Then, while we unroll each partition, periodically check if there is enough space to continue. If not, drop enough RDD blocks to ensure we have at least `M` bytes to work with, then try again. If we still don't have enough space to unroll the partition, give up and drop the block to disk directly if applicable. **New configurations.** - `spark.storage.bufferFraction` - the value of `M` as a fraction of the storage memory. (default: 0.2) - `spark.storage.safetyFraction` - a margin of safety in case size estimation is slightly off. This is the equivalent of the existing `spark.shuffle.safetyFraction`. (default 0.9) For more detail, see the [design document](https://issues.apache.org/jira/secure/attachment/12651793/spark-1777-design-doc.pdf). Tests pending for performance and memory usage patterns.

* [MLlib] SPARK-1536: multiclass classification support for decision treeManish Amde2014-07-181-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ability to perform multiclass classification is a big advantage for using decision trees and was a highly requested feature for mllib. This pull request adds multiclass classification support to the MLlib decision tree. It also adds sample weights support using WeightedLabeledPoint class for handling unbalanced datasets during classification. It will also support algorithms such as AdaBoost which requires instances to be weighted. It handles the special case where the categorical variables cannot be ordered for multiclass classification and thus the optimizations used for speeding up binary classification cannot be directly used for multiclass classification with categorical variables. More specifically, for m categories in a categorical feature, it analyses all the ```2^(m-1) - 1``` categorical splits provided that #splits are less than the maxBins provided in the input. This condition will not be met for features with large number of categories -- using decision trees is not recommended for such datasets in general since the categorical features are favored over continuous features. Moreover, the user can use a combination of tricks (increasing bin size of the tree algorithms, use binary encoding for categorical features or use one-vs-all classification strategy) to avoid these constraints. The new code is accompanied by unit tests and has also been tested on the iris and covtype datasets. cc: mengxr, etrain, hirakendu, atalwalkar, srowen Author: Manish Amde <manish9ue@gmail.com> Author: manishamde <manish9ue@gmail.com> Author: Evan Sparks <sparks@cs.berkeley.edu> Closes #886 from manishamde/multiclass and squashes the following commits: 26f8acc [Manish Amde] another attempt at fixing mima c5b2d04 [Manish Amde] more MIMA fixes 1ce7212 [Manish Amde] change problem filter for mima 10fdd82 [Manish Amde] fixing MIMA excludes e1c970d [Manish Amde] merged master abf2901 [Manish Amde] adding classes to MimaExcludes.scala 45e767a [Manish Amde] adding developer api annotation for overriden methods c8428c4 [Manish Amde] fixing weird multiline bug afced16 [Manish Amde] removed label weights support 2d85a48 [Manish Amde] minor: fixed scalastyle issues reprise 4e85f2c [Manish Amde] minor: fixed scalastyle issues b2ae41f [Manish Amde] minor: scalastyle e4c1321 [Manish Amde] using while loop for regression histograms d75ac32 [Manish Amde] removed WeightedLabeledPoint from this PR 0fecd38 [Manish Amde] minor: add newline to EOF 2061cf5 [Manish Amde] merged from master 06b1690 [Manish Amde] fixed off-by-one error in bin to split conversion 9cc3e31 [Manish Amde] added implicit conversion import 5c1b2ca [Manish Amde] doc for PointConverter class 485eaae [Manish Amde] implicit conversion from LabeledPoint to WeightedLabeledPoint 3d7f911 [Manish Amde] updated doc 8e44ab8 [Manish Amde] updated doc adc7315 [Manish Amde] support ordered categorical splits for multiclass classification e3e8843 [Manish Amde] minor code formatting 23d4268 [Manish Amde] minor: another minor code style 34ee7b9 [Manish Amde] minor: code style 237762d [Manish Amde] renaming functions 12e6d0a [Manish Amde] minor: removing line in doc 9a90c93 [Manish Amde] Merge branch 'master' into multiclass 1892a2c [Manish Amde] tests and use multiclass binaggregate length when atleast one categorical feature is present f5f6b83 [Manish Amde] multiclass for continous variables 8cfd3b6 [Manish Amde] working for categorical multiclass classification 828ff16 [Manish Amde] added categorical variable test bce835f [Manish Amde] code cleanup 7e5f08c [Manish Amde] minor doc 1dd2735 [Manish Amde] bin search logic for multiclass f16a9bb [Manish Amde] fixing while loop d811425 [Manish Amde] multiclass bin aggregate logic ab5cb21 [Manish Amde] multiclass logic d8e4a11 [Manish Amde] sample weights ed5a2df [Manish Amde] fixed classification requirements d012be7 [Manish Amde] fixed while loop 18d2835 [Manish Amde] changing default values for num classes 6b912dc [Manish Amde] added numclasses to tree runner, predict logic for multiclass, add multiclass option to train 75f2bfc [Manish Amde] minor code style fix e547151 [Manish Amde] minor modifications 34549d0 [Manish Amde] fixing error during merge 098e8c5 [Manish Amde] merged master e006f9d [Manish Amde] changing variable names 5c78e1a [Manish Amde] added multiclass support 6c7af22 [Manish Amde] prepared for multiclass without breaking binary classification 46e06ee [Manish Amde] minor mods 3f85a17 [Manish Amde] tests for multiclass classification 4d5f70c [Manish Amde] added multiclass support for find splits bins 46f909c [Manish Amde] todo for multiclass support 455bea9 [Manish Amde] fixed tests 14aea48 [Manish Amde] changing instance format to weighted labeled point a1a6e09 [Manish Amde] added weighted point class 968ca9d [Manish Amde] merged master 7fc9545 [Manish Amde] added docs ce004a1 [Manish Amde] minor formatting b27ad2c [Manish Amde] formatting 426bb28 [Manish Amde] programming guide blurb 8053fed [Manish Amde] more formatting 5eca9e4 [Manish Amde] grammar 4731cda [Manish Amde] formatting 5e82202 [Manish Amde] added documentation, fixed off by 1 error in max level calculation cbd9f14 [Manish Amde] modified scala.math to math dad9652 [Manish Amde] removed unused imports e0426ee [Manish Amde] renamed parameter 718506b [Manish Amde] added unit test 1517155 [Manish Amde] updated documentation 9dbdabe [Manish Amde] merge from master 719d009 [Manish Amde] updating user documentation fecf89a [manishamde] Merge pull request #6 from etrain/deep_tree 0287772 [Evan Sparks] Fixing scalastyle issue. 2f1e093 [Manish Amde] minor: added doc for maxMemory parameter 2f6072c [manishamde] Merge pull request #5 from etrain/deep_tree abc5a23 [Evan Sparks] Parameterizing max memory. 50b143a [Manish Amde] adding support for very deep trees

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Two improvements to the history server: - Separate the HTTP handling from history fetching, so that it's easy to add new backends later (thinking about SPARK-1537 in the long run) - Avoid loading all UIs in memory. Do lazy loading instead, keeping a few in memory for faster access. This allows the app limit to go away, since holding just the listing in memory shouldn't be too expensive unless the user has millions of completed apps in the history (at which point I'd expect other issues to arise aside from history server memory usage, such as FileSystem.listStatus() starting to become ridiculously expensive). I also fixed a few minor things along the way which aren't really worth mentioning. I also removed the app's log path from the UI since that information may not even exist depending on which backend is used (even though there is only one now).

* [SPARK-1395] Fix "local:" URI support in Yarn mode (again).Marcelo Vanzin2014-06-231-3/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent changes ignored the fact that path may be defined with "local:" URIs, which means they need to be explicitly added to the classpath everywhere a remote process is started. This change fixes that by: - Using the correct methods to add paths to the classpath - Creating SparkConf settings for the Spark jar itself and for the user's jar - Propagating those two settings to the remote processes where needed This ensures that both in client and in cluster mode, the driver has the necessary info to build the executor's classpath and have things still work when they contain "local:" references. The change also fixes some confusion in ClientBase about whether to use SparkConf or system properties to propagate config options to the driver and executors, by standardizing on using data held by SparkConf. On the cleanup front, I removed the hacky way that log4j configuration was being propagated to handle the "local:" case. It's much more cleanly (and generically) handled by using spark-submit arguments (--files to upload a config file, or setting spark.executor.extraJavaOptions to pass JVM arguments and use a local file).
