[jira] [Created] (HADOOP-10017) Fix NPE in DFSClient#getDelegationToken when doing Distcp from a secured cluster to an insecured cluster

Jing Zhao created HADOOP-10017:
----------------------------------

             Summary: Fix NPE in DFSClient#getDelegationToken when doing Distcp from a secured cluster to an insecured cluster
                 Key: HADOOP-10017
                 URL: https://issues.apache.org/jira/browse/HADOOP-10017
             Project: Hadoop Common
          Issue Type: Bug
    Affects Versions: 2.1.1-beta, 3.0.0
            Reporter: Jing Zhao
            Assignee: Haohui Mai


Currently if we run Distcp from a secured cluster and copy data to an insecured cluster, DFSClient#getDelegationToken will throw NPE when processing the NULL token returned by the NN in the insecured cluster. We should be able to handle the NULL token here.
