-----------------------------------------------
Pls do not raise JIRA for this. Send out a mail to the User list. Folks will
help you out.
BTW the problem here is i think the MAster is not able to connect to Zookeeper.
Check if there is any firewall and your configs.
The first time when you do JPS the process starts but it gets killed which
means there is a setup/config related issue.
