> 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.
