zk tick time bounds maximum zk session time
-------------------------------------------

                 Key: HBASE-1997
                 URL: https://issues.apache.org/jira/browse/HBASE-1997
             Project: Hadoop HBase
          Issue Type: Bug
            Reporter: stack


Default session is set to 60 seconds but ticktime is 2 seconds.

http://hadoop.apache.org/zookeeper/docs/current/zookeeperProgrammers.html#ch_zkSessions

"One of the parameters to the ZooKeeper client library call to create a 
ZooKeeper session is the session timeout in milliseconds. The client sends a 
requested timeout, the server responds with the timeout that it can give the 
client. The current implementation requires that the timeout be a minimum of 2 
times the tickTime (as set in the server configuration) and a maximum of 20 
times the tickTime."

So, max is actually 40 seconds.
