Subject [jira] [Updated] (PIG-2778) Add 'matches' operator to predicate pushdown
Date Sun, 23 Sep 2012 20:36:08 GMT

     [ https://issues.apache.org/jira/browse/PIG-2778?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Cheolsoo Park updated PIG-2778:
-------------------------------

    Attachment: test_unit.log
                test_e2e.log

Attaching test logs - unit/e2e test.

I see *no regression from this change* although I see some unrelated failures as below:

*Unit test*
- TestInvokerSpeed: known issue PIG-2569
- TestPoissonSampleLoader: known issue PIG-2926
- TestPigServerWithMacros: failed because of an exception during the call to getFileSystem().
Passes when rerun the test. 
- TestStreaming: timeout even without this change.

*e2e test in local mode*
- FilterBoolean_23,24: know issue PIG-2928
- Rank_1,2,3,5,6,7,8,9,10: fail even without this change in trunk.
- The test run hang after executing 474 test cases, so it wasn't complete.

> Currently the regex match operation does not get pushed down to LoadMetadata (and Expression
does not have an enum value for it); it would be quite useful to enable this for some optimizations.
