Hari Mankude commented on HDFS-3192:
------------------------------------
FC via healthmonitor will periodically poll the status of the NN via
getServiceStatus(). If active NN has not heard from FC for timeout number of
seconds, it should exit. This timeout has to be tied to the timeout of the
ephemeral node in zookeeper and it should be a fraction of the ephemeral node
timeout.
This ensures that if FC has died, then active NN also failfasts.
> Active NN should exit when it has not received a getServiceStatus() rpc from
> ZKFC for timeout secs
