                 URL: https://issues.apache.org/jira/browse/HBASE-18452
             Project: HBase

            Reporter: Zheng Hu
            Assignee: Zheng Hu


I've  ported HBASE-16466 to our internal hbase branch,  and tested the feature under our kerberos
cluster.   

The problem we encountered is:

After check the patch,  Seems like we did not obtain the namenode token before submit the
job.  The feature works fine in our kerberos cluster after applied following patch: 

{code}
      TableMapReduceUtil.initTableSnapshotMapperJob(sourceSnapshotName, scan, Verifier.class,
null,
        null, job, true, snapshotTempPath);

      // Acquire the delegation Tokens
+      TokenCache.obtainTokensForNamenodes(job.getCredentials(),
+        new Path[] { new Path(sourceSnapshotTmpDir), new Path(peerSnapshotTmpDir) }, conf);
+
    } 
{code}
