* Merge pull request #297 from tdas/window-improvementPatrick Wendell2014-01-025-15/+45
|\ | | | | | | | | | | | | | | | | Improvements to DStream window ops and refactoring of Spark's CheckpointSuite - Added a new RDD - PartitionerAwareUnionRDD. Using this RDD, one can take multiple RDDs partitioned by the same partitioner and unify them into a single RDD while preserving the partitioner. So m RDDs with p partitions each will be unified to a single RDD with p partitions and the same partitioner. The preferred location for each partition of the unified RDD will be the most common preferred location of the corresponding partitions of the parent RDDs. For example, location of partition 0 of the unified RDD will be where most of partition 0 of the parent RDDs are located. - Improved the performance of DStream's reduceByKeyAndWindow and groupByKeyAndWindow. Both these operations work by doing per-batch reduceByKey/groupByKey and then using PartitionerAwareUnionRDD to union the RDDs across the window. This eliminates a shuffle related to the window operation, which can reduce batch processing time by 30-40% for simple workloads. - Fixed bugs and simplified Spark's CheckpointSuite. Some of the tests were incorrect and unreliable. Added missing tests for ZippedRDD. I can go into greater detail if necessary. - Added mapSideCombine option to combineByKeyAndWindow.

Moved scheduler related code to streaming.scheduler package. - Added StreamingListener trait (similar to SparkListener) to enable gathering to streaming stats like processing times and delays. StreamingContext.addListener() to added listeners. - Deduped some code in streaming tests by modifying TestSuiteBase, and added StreamingListenerSuite.
