Hi,
I have enabled HA in my CDH4 cluster using CM. It can run successfully
without enabling the automatic failover.
but, While "Enabling Automatic Failover", it is unable to initialize HA in
zookeeper. It gives the following error message:
Failed to initialize High Availability state in ZooKeeper from

Why can not enabling the automatic failover?
Thanks,
