Todd Lipcon updated HDFS-3042:
------------------------------

    Attachment: hdfs-3042.txt

Attaching a diff of the branch vs trunk, to try to get a hadoop-qa run on it. I've run tests
and findbugs manually locally, but I want to verify that hadoop-QA agrees.

> 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.
