Description

In our hadoop cluster, we specified ports of zk servers in hbase.zookeeper.quorum of hbase-site.xml like
<property>
<name>hbase.zookeeper.quorum</name>
<value>hadoop1:2181,hadoop2:2181,hadoop3:2181</value>
</property>
And we get the error "ERROR [Thread-12] curator.ConnectionState:201 : Connection timed out for connection string (hadoop1:2181:2181,hadoop2:2181:2181,hadoop3:2181:2181) and timeout (15000) / elapsed (15214)"

I think org.apache.kylin.storage.hbase.util.ZookeeperJobLock#getZKConnectString should check whether it ends with a port before adding a port to the string.

Attached is the patch.
