Description
When attempting to access files provided by the Distributed Cache the DistributedCache.getLocalCacheFiles() method returns NULL.
The files are set via DistributedCache.setCacheFiles() and can be retrieved later via DistributedCache.getCacheFiles().
It seems, that the files are not copied to the local file system by Hama.
I think this bug is similar to https://issues.apache.org/jira/browse/MRUNIT-124
