Subject [jira] [Created] (HDFS-2473) Fetching tokens from insecure cluster throws NPEs

Fetching tokens from insecure cluster throws NPEs

                 Key: HDFS-2473
                 URL: https://issues.apache.org/jira/browse/HDFS-2473
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: hdfs client
    Affects Versions:
            Reporter: Daryn Sharp
            Priority: Critical

Retrieving tokens from an insecure cluster throws an NPE.  This prevents copies from insecure
to secure clusters.  The problem is in {{DFSClient.getDelegationToken()}}.  It attempts to
set the service and log the token w/o a null check.

FetchDT will also throw exceptions when fetching tokens from an insecure cluster.
