Subject Does the JobHistoryServer register itself with ZooKeeper?
Date Wed, 16 Nov 2016 19:32:00 GMT
I'm looking for a way to check for connectivity to the JobHistoryServer.

One way I can think of is to create a Socket connection (in Java code) to
the JobHistoryServer IPC port specified in mapreduce.jobhistory.address.

If the JHS registers itself with ZooKeeper, is there a way for me to ping
ZooKeeper to check the status of the JHS?
