Review request for hive.
Changes
-------
bug fix
Description
-------
This optimizer exploits intra-query correlations and merges multiple correlated
MapReduce jobs into one jobs. Open a new request since I have been working on
hive-git.
This addresses bug HIVE-2206.

Testing
-------
Cannot test TestHBaseMinimrCliDriver, TestHBaseCliDriver,
TestHBaseNegativeCliDriver, testSynchronized in TestEmbeddedHiveMetaStore,
testSynchronized in TestRemoteHiveMetaStore, testSynchronized in
TestSetUGIOnBothClientServer, testSynchronized in TestSetUGIOnOnlyClient,
testSynchronized in TestSetUGIOnOnlyServer, and
testNegativeCliDriver_local_mapred_error_cache in TestNegativeCliDriver, since
trunk failed on these tests on my machine. Also, since trunk will generate a
different order of results (rows are in a different order) for queries
skewjoinopt1.q to skewjoinopt5.q, skewjoinopt10.q, skewjoinopt15.q to
skewjoinopt17.q, and skewjoinopt19.q to skewjoinopt20.q, I cannot test these
queries on my machine either. All other tests pass.
Thanks,
Yin Huai
