Joydeep Sen Sarma commented on HIVE-1463:
-----------------------------------------
if u look at the testFileSinkOperator in trunk - it's useless. it doesn't test
FileSinkOperator at all. I noted down in the comments - hive-405 took out the
test for filesinkoperator. without that - the test is just testing the select
operator - and this is tested elsewhere in the same file anyway.
so i took out the old code and left a comment that this test needs to be
enhanced to cover FileSinkOperator more comprehensively in the future.
> hive output file names are unnecessarily large

> Hive's output files are named like this:
> attempt_201006221843_431854_r_000000_0
> out of all of this goop - only one character '0' would have sufficed. we
> should fix this. This would help environments with namenode memory
> constraints.
