Subject [jira] [Updated] (HIVE-2206) add a new optimizer for query correlation discovery and optimization
Date Sat, 15 Sep 2012 23:20:08 GMT

     [ https://issues.apache.org/jira/browse/HIVE-2206?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Yin Huai updated HIVE-2206:
---------------------------

    Attachment: HIVE-2206.11-r1385084.patch.txt

new patch for trunk (revision 1385084). Disabled the optimizer by default and updated test
results.

[~he yongqiang]:
can you help me test a few cases which the trunk on my machine cannot pass?
Those are 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.
Thanks!
