JobTracker.finalizeJob inverts lock order and causes potential deadlock
-----------------------------------------------------------------------

                 Key: MAPREDUCE-1499
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1499
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: jobtracker
    Affects Versions: 0.20.1, 0.20.2
            Reporter: Todd Lipcon
            Priority: Critical


This issue was brought up by Matei in MAPREDUCE-1436 as a fairsched bug, but it turns out
it's a JT bug even with the fifo scheduler in unpatched 0.20.2. JobTracker.finalizeJob locks
JT.jobs, JT.taskScheduler, etc, having gotten the JIP log before the JT lock.
