[jira] [Created] (ZOOKEEPER-3916) check whether zookeeperServer is null or not before being used

Pengfei Yan created ZOOKEEPER-3916:
--------------------------------------

             Summary: check whether  zookeeperServer is null or not before being used 
                 Key: ZOOKEEPER-3916
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3916
             Project: ZooKeeper
          Issue Type: Improvement
          Components: server
            Reporter: Pengfei Yan


If the zookeeperServer object is null, then the client can't make connections with servers because the Leader Voting stage is working. After checking the Object we can avoid null pointer exception and give the IOException and close connections.
