Re: Zookeeper is not communicating
Hi Aditya, it's likely that your ZK quorum has not formed correctly
"ZooKeeperServer not running" (at least 2 of the 3 servers need to be
talking). Try using the four letter words to verify (srvr).
http://zookeeper.apache.org/doc/r3.4.5/zookeeperAdmin.html#sc_zkCommands

Check the zk server logs for more details on whether the quorum can
form and why not.
