HA: Checkpointing in an HA setup
--------------------------------

                 Key: HDFS-2291
                 URL: https://issues.apache.org/jira/browse/HDFS-2291
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: name-node
    Affects Versions: HA branch (HDFS-1623)
            Reporter: Aaron T. Myers
            Assignee: Todd Lipcon
             Fix For: HA branch (HDFS-1623)


We obviously need to create checkpoints when HA is enabled. One thought is to use a third,
dedicated checkpointing node in addition to the active and standby nodes. Another option would
be to make the standby capable of also performing the function of checkpointing.
