Description
MAPREDUCE-842 enforces that mapred.local.dir for Task to be attemptDirs in all local dirs. The conf is not set to attemptDirs for IsolationRunner.
So, the map output files are created directly under Cluster's local dir. The same can be seen in TestIsolationRunner. Test does not fail because it is not validated.
