> MiniMRCluster's JobTracker sets the mapred.local.dir to a relative path: "build/test/mapred/local".
While currently this does not cause any problem, if at some time in future, the JobTracker
starts using LocalDirAllocator for localizing files, this could cause failures in contrib
tests. This issue was faced when working with an internal patch that tried to introduce LocalDirAllocator
into the JobTracker, and capacity scheduler test cases started failing.
