No, my zk server is same with Master sever.

<description>Comma separated list of servers in the ZooKeeper Quorum.
For example,
"host1.mydomain.com,host2.mydomain.com,host3.mydomain.com".
By default this is set to localhost for local and pseudo-distributed
modes
of operation. For a fully-distributed setup, this should be set to a
full
list of ZooKeeper quorum servers. If HBASE_MANAGES_ZK is set in
hbase-env.sh
this is the list of servers which we will start/stop ZooKeeper on.

Anything's wrong?

Please respond to
hbase-user
Are your zk servers the same as the hbase regionservers?
What is your setup?
What were the warn messages? Can you post them here?
