      Description

      LocalDirAllocator.ifExists calls AllocatorPerContext.ifExists, which accesses the localDirsPath variable that is uninitialised. Hence, any code that uses this API is likely to fail with a NullPointerException.

      However, this API is currently not used anywhere else in trunk. The earlier usage was in IsolationRunner, that has since been removed via MAPREDUCE-2606.

      Hence, we could remove this API for trunk, and if required, fix it for the 1.x branch.
