Summary: VerifyReplication by Snapshot should cache HDFS token
before submit job for kerberos env.
Key: HBASE-18452

Project: HBase
Issue Type: Bug
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}
