-------------------------------
Summary: pig job hang if the job tracker is bounced during
execution
Key: PIG-3313
URL: https://issues.apache.org/jira/browse/PIG-3313
Project: Pig
Issue Type: Bug
Reporter: Chenjie Yu
When running a pig job through PigRunner, after the mapreduce job is submitted,
if there is a job tracker bounce which doesn't get back up very soon, the pig
job will hang there.
The reason is pig is keeping all the JobControl objects, which are non-deamon
threads, that keeps connecting to jobtracker. If the job tracker is down, pig
will fail, but those jobcontrol threads keep running and there is no one who
can stop them.
