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.
> Add 'matches' operator to predicate pushdown

> 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.
