Karthik Kambatla commented on MAPREDUCE-5131:
---------------------------------------------
The second patch definitely looks good. Thanks Arun.
Minor comments:
# JobTracker#setInitDone() shouldn't need to take any parameter, no? Currently,
it is only the test using it, but this can change.
# JobTracker#waitForInit() shouldn't we do something when we catch the
InterruptedException - at the least, logging it might help
# JobTracker#waitForInit() - adding a log message that we are about to wait
should help
# RetryUtils#getDefaultRetryPolicy() - break after setting found?
> Provide better handling of job status related apis during JT restart

> I've seen pig/hive applications bork during JT restart since they get NPEs -
> this is due to fact that jobs are not really inited, but are submitted.
