          This is going to break MapReduce since JobSubmitter.printTokens(..) is using DFSClient.stringifyToken(..).

          Hi Nicholas,

          I have reviewd this patch.
          I have checked the referances in Mapreduce & Hbase as well.
          In Above comment, you already mentioned that MapReduce is using that DFSClient.stringifyToken.

           LOG.debug("Submitting with " +
                        DFSClient.stringifyToken((Token<org.apache.hadoop.hdfs.security.token.delegation.DelegationTokenIdentifier>) token));
          

          can we raise one Jira for that in MapReduce?

          +1 Patch looks good to me.
          We should co-ordinate to comitt both(mapred + hdfs issue) at same time to avoid the breakage in Mapreduce.

          small nits,
          1. i did not see any big advantage by moving the random object, other than the object creations. If any big advantage then we will plan ,to move it to common utils. So, that we can change in mapred side also to use .

          2. Now stringifyToken moved to DelegationTokenIdentifier, looks Mepred also has one DelegationTokenIdentifier please check. Can we think some common place for it?

          We can check this nits from Mepreduce issue.

          Hi Uma, thanks for reviewing my patch.

          I have created MAPREDUCE-2710 for updating JobSubmitter.printTokens(..).

          > 1. i did not see any big advantage by moving the random object ...

          My main motivation is to clean up the code. There are many Random objects floating around. In some cases, the object is not used, e.g. HftpFileSystem. In some other cases, there are two objects created in the same class, e.g. FSDataset. I also believe there are synchronization issue – there are race conditions when two threads access the same Random object at the same time. Fortunately, it is very unlikely that why we have not observed the problem.

          > 2. Now stringifyToken moved to DelegationTokenIdentifier ...

          The one in MapReduce may have different fields. So they may need different methods.
