* [SPARK-8850] [SQL] Enable Unsafe mode by defaultJosh Rosen2015-07-307-24/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This pull request enables Unsafe mode by default in Spark SQL. In order to do this, we had to fix a number of small issues: **List of fixed blockers**: - [x] Make some default buffer sizes configurable so that HiveCompatibilitySuite can run properly (#7741). - [x] Memory leak on grouped aggregation of empty input (fixed by #7560 to fix this) - [x] Update planner to also check whether codegen is enabled before planning unsafe operators. - [x] Investigate failing HiveThriftBinaryServerSuite test. This turns out to be caused by a ClassCastException that occurs when Exchange tries to apply an interpreted RowOrdering to an UnsafeRow when range partitioning an RDD. This could be fixed by #7408, but a shorter-term fix is to just skip the Unsafe exchange path when RangePartitioner is used. - [x] Memory leak exceptions masking exceptions that actually caused tasks to fail (will be fixed by #7603). - [x] ~~https://issues.apache.org/jira/browse/SPARK-9162, to implement code generation for ScalaUDF. This is necessary for `UDFSuite` to pass. For now, I've just ignored this test in order to try to find other problems while we wait for a fix.~~ This is no longer necessary as of #7682. - [x] Memory leaks from Limit after UnsafeExternalSort cause the memory leak detector to fail tests. This is a huge problem in the HiveCompatibilitySuite (fixed by f4ac642a4e5b2a7931c5e04e086bb10e263b1db6). - [x] Tests in `AggregationQuerySuite` are failing due to NaN-handling issues in UnsafeRow, which were fixed in #7736. - [x] `org.apache.spark.sql.ColumnExpressionSuite.rand` needs to be updated so that the planner check also matches `TungstenProject`. - [x] After having lowered the buffer sizes to 4MB so that most of HiveCompatibilitySuite runs: - [x] Wrong answer in `join_1to1` (fixed by #7680) - [x] Wrong answer in `join_nulls` (fixed by #7680) - [x] Managed memory OOM / leak in `lateral_view` - [x] Seems to hang indefinitely in `partcols1`. This might be a deadlock in script transformation or a bug in error-handling code? The hang was fixed by #7710. - [x] Error while freeing memory in `partcols1`: will be fixed by #7734. - [x] After fixing the `partcols1` hang, it appears that a number of later tests have issues as well. - [x] Fix thread-safety bug in codegen fallback expression evaluation (#7759).

* [SPARK-5561] [MLLIB] Generalized PeriodicCheckpointer for RDDs and GraphsJoseph K. Bradley2015-07-306-99/+452
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PeriodicGraphCheckpointer was introduced for Latent Dirichlet Allocation (LDA), but it was meant to be generalized to work with Graphs, RDDs, and other data structures based on RDDs. This PR generalizes it. For those who are not familiar with the periodic checkpointer, it tries to automatically handle persisting/unpersisting and checkpointing/removing checkpoint files in a lineage of RDD-based objects. I need it generalized to use with GradientBoostedTrees [https://issues.apache.org/jira/browse/SPARK-6684]. It should be useful for other iterative algorithms as well. Changes I made: * Copied PeriodicGraphCheckpointer to PeriodicCheckpointer. * Within PeriodicCheckpointer, I created abstract methods for the basic operations (checkpoint, persist, etc.). * The subclasses for Graphs and RDDs implement those abstract methods. * I copied the test suite for the graph checkpointer and made tiny modifications to make it work for RDDs. To review this PR, I recommend doing 2 diffs: (1) diff between the old PeriodicGraphCheckpointer.scala and the new PeriodicCheckpointer.scala (2) diff between the 2 test suites CCing andrewor14 in case there are relevant changes to checkpointing. CCing feynmanliang in case you're interested in learning about checkpointing. CCing mengxr for final OK. Thanks all! Author: Joseph K.

* [SPARK-7368] [MLLIB] Add QR decomposition for RowMatrixYuhao Yang2015-07-303-1/+70
| | | | | | | | | | | | | | | | | | | | | | | | | | jira: https://issues.apache.org/jira/browse/SPARK-7368 Add QR decomposition for RowMatrix. I'm not sure what's the blueprint about the distributed Matrix from community and whether this will be a desirable feature , so I sent a prototype for discussion. I'll go on polish the code and provide ut and performance statistics if it's acceptable. The implementation refers to the [paper: https://www.cs.purdue.edu/homes/dgleich/publications/Benson%202013%20-%20direct-tsqr.pdf] Austin R. Benson, David F. Gleich, James Demmel. "Direct QR factorizations for tall-and-skinny matrices in MapReduce architectures", 2013 IEEE International Conference on Big Data, which is a stable algorithm with good scalability. Currently I tried it on a 400000 * 500 rowMatrix (16 partitions) and it can bring down the computation time from 8.8 mins (using breeze.linalg.qr.reduced) to 2.6 mins on a 4 worker cluster. I think there will still be some room for performance improvement. Any trial and suggestion is welcome.
