-----------------------------------------
There are no unit test cases as the testing was performed manually. Pasting a
test run below.

$ cat /errcode.pig
a = load '/user/sms/data/student_tab.data' ;
b = stream a through `false` ;
store b into '/user/sms/data/errcode.out';

> incorrect return codes on failure when using -f or -e flags
> -----------------------------------------------------------

> Key: PIG-839
> URL: https://issues.apache.org/jira/browse/PIG-839
> Project: Pig
> Issue Type: Bug
> Reporter: Gunther Hagleitner
> Assignee: Gunther Hagleitner
> Attachments: fix_return_code.patch
>
>
> To repro: pig -e "a = load '<some file>' ; b = stream a through \`false\` ;
> store b into '<some file>';"
> Both the -e and -f flags do not return the right code upon exit. Running the
> script w/o using -f works fine.
