> When investigating PIG-4972, I also notice Pig job stuck when the perl script have syntax error. This happens if we have output clause in stream specification (means use a file as staging). The bug exist in both Tez and MR, and it is not a regression.
> Here is an example:
> {code}
> define CMD `perl kk.pl` output('foo') ship('kk.pl');
> A = load 'studenttab10k' as (name, age, gpa);
> B = foreach A generate name;
> C = stream B through CMD;
> store C into 'ooo';
> {code}
> kk.pl is any perl script contain a syntax error.
