JobHistory.markCompleted() should be synchronized
-------------------------------------------------
Key: MAPREDUCE-795
URL: https://issues.apache.org/jira/browse/MAPREDUCE-795
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: jobtracker
Reporter: Amar Kamat
Assignee: Amar Kamat
Since other FS calls in JobHistory are synchronized, this call should also be
synchronized. This method moves jobhistory files from running to done folder.
So while other JobHistory methods perform a search in the running folder this
method might move the files in the FS causing inconsistencies.
