Harsh J commented on HDFS-3918:
-------------------------------
Change looks good, but just so that the string change not cause an issue later
(since we are apparently splitting it), can we have some form of
regression-catch to ensure [0] is always what we want it to be?
Not very necessary, but would be good to have. If its tough to do, we can punt.
+1 with this addressed (in reply or in patch).

> If both nodes are in standby mode, each will be trying to roll the others'
> logs, which results in errors like:
> Unable to trigger a roll of the active NN
> org.apache.hadoop.ipc.StandbyException: Operation category JOURNAL is not
> supported in state standby
> We should catch this specific exception and not log it at WARN level, since
> it's expected behavior.
