            Description

            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.
