Binglin Chang commented on MAPREDUCE-2364:
------------------------------------------
We encounter the same problem, when TaskTracker download & unJar a very big
job.jar in localizeJob(), it stops sending heartbeat and web service hangs too.
Our solution for this issue is to add a new lock in RunningJob class called
localizing. Instead of holding the whole rjob lock, rjob.localizing is locked.
> Shouldn't hold lock on rjob while localizing resources.
