> HDFS-1623 was the umbrella task for implementation of NN HA capabilities. However, it
only focused on manually-triggered failover.
> Given that the HDFS-1623 branch will be merged shortly, I'm opening this JIRA to consolidate/track
subtasks for automatic failover support and related improvements.
