Rohini Palaniswamy commented on PIG-3641:
-----------------------------------------
TestScriptLanguage.runParallelTest2 also failed. That is also unrelated. Will
file a jira to fix both.
> Split "otherwise" producing incorrect output when combined with ColumnPruning

> Our user was observing incorrect outputs depending on if the query had
> intermediate output or not. Below is a simplified testcase I came up with.

> knoguchi pig> cat bz-6590644/test.pig
> A = load 'test.txt' using PigStorage(',') as (a1:int, a2:int, a3:chararray);
> B = foreach A generate a1,a2;
> SPLIT B into C1 if a2 == 1, D1 otherwise;
> C2 = foreach C1 generate a2;
> store C2 into '/tmp/testC';
> store D1 into '/tmp/testD';

> Incorrect output shown below. /tmp/testD should be empty but somehow has
> data in it.
