Aaron T. Myers updated HDFS-2952:
---------------------------------
Attachment: HDFS-2952-HDFS-1623.patch
Here's a little patch which addresses the issue. An HA NN already refused to
start if a previous upgrade was in progress, but this patch adds a test for the
behavior.
I also took the liberty of fixing 3 little typos I noticed while preparing this
patch.
> HA: NN should not start with upgrade option or with a pending an unfinalized
> upgrade
