> Ambari upgrade from 1.7.0 to 2.0.0 had problems on starting/restarting zookeeper server because /usr/hdp/current/zookeeper-server symlink was not found. The customer remedied the issue by calling "hdp-select set zookeeper-server 2.2.3.0-###" on all of the hosts, which created the symlink.
> In Ambari 1.7.0, ZK server was started using the libs from ZK client, so as part of the Ambari Upgrade, we need to first call "hdp-select set zookeeper-server
> {version}
> "
> It's possible that the either exactly one of start/restart command will handle this. Need to verify what the behavior is.
