> 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}
