Description

The actual error message is:

Inconsistent synchronization of org.apache.hadoop.mapreduce.v2.app.rm.RMContainerAllocator.reduceNodeLabelExpression; locked 66% of time

The full URL for the findbugs is at:

https://builds.apache.org/job/PreCommit-MAPREDUCE-Build/5858/artifact/patchprocess/trunkFindbugsWarningshadoop-mapreduce-client-app.html

I haven't looked to see if this message is in error or if findbugs is correct.
