* SPARK-2026: Maven Hadoop Profiles Should Set The Hadoop VersionBernardo Gomez Palacio2014-06-081-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Maven Profiles that refer to hadoopX, e.g. `hadoop2.4`, should set the expected `hadoop.version` and `yarn.version`. e.g. ``` <profile> <id>hadoop-2.4</id> <properties> <hadoop.version>2.4.0</hadoop.version> <yarn.version>${hadoop.version}</yarn.version> <protobuf.version>2.5.0</protobuf.version> <jets3t.version>0.9.0</jets3t.version> </properties> </profile> ``` Builds can still define the `-Dhadoop.version` option but this will correctly default the Hadoop Version to the one that is expected according the profile that is selected. e.g. ```$ mvn -P hadoop-2.4,yarn clean install``` or ```$ mvn -P hadoop-0.23,yarn clean install``` [ticket] : https://issues.apache.org/jira/browse/SPARK-2026 Author : berngp Reviewer : ?

| | | | | | | | | | | | | | in HDFS Basically there is a race condition (possibly a scala bug?) when these values are recomputed on all of the slaves that results in an incorrect projection being generated (possibly because the GUID uniqueness contract is broken?).

* [SPARK-1552] Fix type comparison bug in {map,outerJoin}VerticesAnkur Dave2014-06-055-8/+40
| | | | | | | | | | | | | | | | | | | | | In GraphImpl, mapVertices and outerJoinVertices use a more efficient implementation when the map function conserves vertex attribute types. This is implemented by comparing the ClassTags of the old and new vertex attribute types. However, ClassTags store erased types, so the comparison will return a false positive for types with different type parameters, such as Option[Int] and Option[Double]. This PR resolves the problem by requesting that the compiler generate evidence of equality between the old and new vertex attribute types, and providing a default value for the evidence parameter if the two types are not equal. The methods can then check the value of the evidence parameter to see whether the types are equal. It also adds a test called "mapVertices changing type with same erased type" that failed before the PR and succeeds now. Callers of mapVertices and outerJoinVertices can no longer use a wildcard for a graph's VD type. To avoid "Error occurred in an application involving default arguments," they must bind VD to a type parameter, as this PR does for ShortestPaths and LabelPropagation.

* SPARK-2043: ExternalAppendOnlyMap doesn't always find matching keysMatei Zaharia2014-06-052-5/+44
| | | | | | | | | | | The current implementation reads one key with the next hash code as it finishes reading the keys with the current hash code, which may cause it to miss some matches of the next key. This can cause operations like join to give the wrong result when reduce tasks spill to disk and there are hash collisions, as values won't be matched together. This PR fixes it by not reading in that next key, using a peeking iterator instead. Author: Matei Zaharia <matei@databricks.com> Closes #986 from mateiz/spark-2043 and squashes the following commits: 0959514 [Matei Zaharia] Added unit test for having many hash collisions 892debb [Matei Zaharia] SPARK-2043: don't read a key with the next hash code in ExternalAppendOnlyMap, instead use a buffered iterator to only read values with the current hash code.
* [SPARK-2025] Unpersist edges of previous graph in PregelAnkur Dave2014-06-051-0/+1
| | | | | | | | | | | | | | Due to a bug introduced by apache/spark#497, Pregel does not unpersist replicated vertices from previous iterations. As a result, they stay cached until memory is full, wasting GC time. This PR corrects the problem by unpersisting both the edges and the replicated vertices of previous iterations. This is safe because the edges and replicated vertices of the current iteration are cached by the call to `g.cache()` and then materialized by the call to `messages.count()`. Therefore no unmaterialized RDDs depend on `prevG.edges`. I verified that no recomputation occurs by running PageRank with a custom patch to Spark that warns when a partition is recomputed. Thanks to Tim Weninger for reporting this bug.

* [SPARK-1752][MLLIB] Standardize text format for vectors and labeled pointsXiangrui Meng2014-06-0418-72/+579
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We should standardize the text format used to represent vectors and labeled points. The proposed formats are the following: 1. dense vector: `[v0,v1,..]` 2. sparse vector: `(size,[i0,i1],[v0,v1])` 3. labeled point: `(label,vector)` where "(..)" indicates a tuple and "[...]" indicate an array. `loadLabeledPoints` is added to pyspark's `MLUtils`. I didn't add `loadVectors` to pyspark because `RDD.saveAsTextFile` cannot stringify dense vectors in the proposed format automatically. `MLUtils#saveLabeledData` and `MLUtils#loadLabeledData` are deprecated. Users should use `RDD#saveAsTextFile` and `MLUtils#loadLabeledPoints` instead. In Scala, `MLUtils#loadLabeledPoints` is compatible with the format used by `MLUtils#loadLabeledData`.

* SPARK-1973. Add randomSplit to JavaRDD (with tests, and tidy Java tests)Sean Owen2014-06-044-334/+358
| | | | | | | | | | | | | | | | | | | | | I'd like to use randomSplit through the Java API, and would like to add a convenience wrapper for this method to JavaRDD. This is fairly trivial.

* [SPARK-1991] Support custom storage levels for vertices and edgesAnkur Dave2014-06-038-97/+229
| | | | | | | | | | | | | | | | | | | | | This PR adds support for specifying custom storage levels for the vertices and edges of a graph. This enables GraphX to handle graphs larger than memory size by specifying MEMORY_AND_DISK and then repartitioning the graph to use many small partitions, each of which does fit in memory. Spark will then automatically load partitions from disk as needed. The user specifies the desired vertex and edge storage levels when building the graph by passing them to the graph constructor. These are then stored in the `targetStorageLevel` attribute of the VertexRDD and EdgeRDD respectively. Whenever GraphX needs to cache a VertexRDD or EdgeRDD (because it plans to use it more than once, for example), it uses the specified target storage level. Also, when the user calls `Graph#cache()`, the vertices and edges are persisted using their target storage levels. In order to facilitate propagating the target storage levels across VertexRDD and EdgeRDD operations, we remove raw calls to the constructors and instead introduce the `withPartitionsRDD` and `withTargetStorageLevel` methods. I tested this change by running PageRank and triangle count on a severely memory-constrained cluster (1 executor with 300 MB of memory, and a 1 GB graph). Before this PR, these algorithms used to fail with OutOfMemoryErrors. With this PR, and using the DISK_ONLY storage level, they succeed.

* Synthetic GraphX BenchmarkJoseph E. Gonzalez2014-06-034-11/+171
| | | | | | | | | | | | | | | | | | | | This PR accomplishes two things: 1. It introduces a Synthetic Benchmark application that generates an arbitrarily large log-normal graph and executes either PageRank or connected components on the graph. This can be used to profile GraphX system on arbitrary clusters without access to large graph datasets 2. This PR improves the implementation of the log-normal graph generator. Author: Joseph E.

* [SPARK-1912] fix compress memory issue during reduceWenchen Fan(Cloud)2014-06-031-2/+20
| | | | | | | | | | | | | | | | When we need to read a compressed block, we will first create a compress stream instance(LZF or Snappy) and use it to wrap that block. Let's say a reducer task need to read 1000 local shuffle blocks, it will first prepare to read that 1000 blocks, which means create 1000 compression stream instance to wrap them. But the initialization of compression instance will allocate some memory and when we have many compression instance at the same time, it is a problem. Actually reducer reads the shuffle blocks one by one, so we can do the compression instance initialization lazily.

The `unwrapHiveData` function is now composed statically before actual rows are scanned according to the field object inspector to avoid dynamic dispatching cost. According to the same micro benchmark used in PR #758, this simple change brings slight performance boost: 2.5% for CSV table and 1% for RCFile table. ``` Optimized version: CSV: 6870 ms, RCFile: 5687 ms CSV: 6832 ms, RCFile: 5800 ms CSV: 6822 ms, RCFile: 5679 ms CSV: 6704 ms, RCFile: 5758 ms CSV: 6819 ms, RCFile: 5725 ms Original version: CSV: 7042 ms, RCFile: 5667 ms CSV: 6883 ms, RCFile: 5703 ms CSV: 7115 ms, RCFile: 5665 ms CSV: 7020 ms, RCFile: 5981 ms CSV: 6871 ms, RCFile: 5906 ms ``` Author: Cheng Lian <lian.cs.zju@gmail.com> Closes #935 from liancheng/staticUnwrapping and squashes the following commits: c49c70c [Cheng Lian] Avoid dynamic dispatching when unwrapping Hive data.
