    HADOOP-6551, HDFS-986, MAPREDUCE-1503. Change API for tokens to throw
    exceptions instead of returning booleans. (omalley)

    +    HADOOP-6551, HDFS-986, MAPREDUCE-1503. Change API for tokens to throw
    +    exceptions instead of returning booleans. (omalley)
    +
    +    HADOOP-6572. Makes sure that SASL encryption and push to responder queue
    +    for the RPC response happens atomically. (Kan Zhang via ddas)
    +    HADOOP-6559. Makes the RPC client automatically re-login when the SASL
    +    connection setup fails. This is applicable to only keytab based logins.
    +    (ddas)
    +    HADOOP-6552. Puts renewTGT=true and useTicketCache=true for the keytab
    +    kerberos options. (ddas)
    +    HADOOP-6547, HDFS-949, MAPREDUCE-1470. Move Delegation token into Common
    +    so that we can use it for MapReduce also. It is a combined patch for
    +    common, hdfs and mr. (jitendra)
    +    HADOOP-6510,HDFS-935,MAPREDUCE-1464. Support for doAs to allow
    +    authenticated superuser to impersonate proxy users. It is a combined
    +    patch with compatible fixes in HDFS and MR. (jitendra)
    +    MAPREDUCE-1457. Fixes JobTracker to get the FileSystem object within
    +    getStagingAreaDir within a privileged block. Fixes Child.java to use the
    +    appropriate UGIs while getting the TaskUmbilicalProtocol proxy and while
    +    executing the task. Contributed by Jakob Homan. (ddas)
    +    Distributed Cache and Distcp. Also, provides a config
    +    mapreduce.job.hdfs-servers that the jobs can populate with a comma
    +    separated list of namenodes. The job client automatically fetches
    +    delegation tokens from those namenodes.
    +    HADOOP-4656, HDFS-685, MAPREDUCE-1083. Use the user-to-groups mapping
    +    service in the NameNode and JobTracker. Combined patch for these 3 jiras
    +    otherwise tests fail. (Jitendra Nath Pandey)
    +    HDFS-781. Namenode metrics PendingDeletionBlocks is not decremented.
    +    (suresh)
