zookeeper unable to start on hdp 2.3.2

[#1]

Unable to start zookeeper, getting following error:

Could not find or load main class org.apache.zookeeper.server.quorum.QuorumPeerMain

Just check if you are running into multinode cluster and facing timeout issue below:-

https://issues.apache.org/jira/browse/ZOOKEEPER-1213

If you are running single node what is the result of

./zookeeper/bin/zkServer.sh start

[#3]

nope it's not timeout issue, see my error its related to library issue I guess. Anyway here is the start output

It is probably not running.

Issue is resolved after deleting the zookeeper services and reinstalling. Unable to start the service due to improper configuration of the service.
