> Project: Hadoop HDFS
> Issue Type: Sub-task

> 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.
