-------------------------------------------
Summary: FairScheduler#dump()'s body is unnecessarily synchronized
on eventLog
Key: MAPREDUCE-4707
URL: https://issues.apache.org/jira/browse/MAPREDUCE-4707
Project: Hadoop Map/Reduce
Issue Type: Improvement
Components: contrib/fair-share
Affects Versions: 1.0.3
Reporter: Karthik Kambatla
Assignee: Karthik Kambatla
FairScheduler#dump() is a synchronized method. In addition to that, the entire
method body is in a synchronized block on eventLog. However, there is no other
portion of the code that tries to acquire a lock on eventLog. So, it seems like
the second synchronized block is redundant, and can be removed.
