Hari Mankude commented on HDFS-3192:
------------------------------------
bq.Why?
I think it's an advantage that the FC may die and come back, or that you may
start the FCs after the NNs.
Well, if FC restarts the health monitoring within the timeout period, then NN
will not die. However, if FC is having a gc pause or is not restarting, then NN
should die. This is the first level of protection where in if NN is healthy, it
can stonith itself.
> Active NN should exit when it has not received a getServiceStatus() rpc from
> ZKFC for timeout secs
