[jira] Resolved: (PIG-192) "Broken pipe" if the streaming
script/binary does not read from STDIN
[ https://issues.apache.org/jira/browse/PIG-192?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Arun C Murthy resolved PIG-192.
-------------------------------
Resolution: Fixed

cat input.txt | PigLoggingTest 10 f

PigLoggingTest _is_ reading from stdin in the shell too... if you do not want it to read from stdin you need to specify a *input* spec in your DEFINE ...

> I got "broken pipe" exceptions if the streaming script/binary does not read from STDIN. I would expect the streaming still to come through. For instance, on the shell command line I can issue:
> {code}
> cat input.txt | PigLoggingTest 10 f
> {code}
> and this does not generate any error even though PigLoggingTest in this case does not read from STDIN at all.
> However, if I use the same command in Pig streaming I get "broken pipe".
> {code}
> A = load '../../singlefile/studenttab10k';
> B = stream A through `PigLoggingTest 10 f` as (name, age, gpa);
> store B into 'results_14';
> {code}
