> Pig stoped at progress 56%.   It seemed there had been exceptions on the the reduce task trackers (see below).  But waiting for 20 reduce tasks to time out themselves is excruciating and blocking my other tests.
> Here is my Pig script:
> {code}
> define X `DataGuaranteeTest.pl -n 1` ship('/home/xu/streamingscript/DataGuaranteeTest.pl');
> A = load '/user/pig/tests/data/singlefile/studenttab10k' as (name, age, gpa);
> B = group A by name;
> C = foreach B generate flatten(A);
> D = stream C through X;
> store D into 'results_24';
> {code}
> Here is the exception on the reduce task trackers:
> {noformat}
> java.lang.RuntimeException: java.io.IOException: Cannot run program "./home/xu/streamingscript/DataGuaranteeTest.pl": java.io.IOException: error=2, No such file or directory
