Eli Collins updated HADOOP-7924:
--------------------------------
Attachment: hadoop-7924.txt
#1 Done
#2 Added missing catch Exception in transitionToActive
#3-4 Done
#5 Just removed the test. Think the typo case I mentioned above is worth
worrying about or a non-issue since we let people explicitly transition more
than one NN to active (and have to handle that fallout)?
#6 The "cluster" was running on one host, though yes, the failover is done
between two independent NN processes running with HA enabled using a shared dir.
