---------------------------------------------------------

             Summary: Possible NPE at ClientDistributedCacheManager#determineTimestamps
                 Key: MAPREDUCE-4395
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4395
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: distributed-cache, job submission, mrv2
    Affects Versions: 3.0.0
            Reporter: Bhallamudi Venkata Siva Kamesh
            Assignee: Bhallamudi Venkata Siva Kamesh


{code:title=ClientDistributedCacheManager#determineTimestamps|borderStyle=solid}
URI[] tfiles = DistributedCache.getCacheFiles(job);
{code}

It may be possible that tfiles array contains *null* as it's entry, and subsequently leads to NPE.
