             Summary: Wait for connection attempt to succeed before performing operations on ZK
                 Key: HBASE-24972
                 URL: https://issues.apache.org/jira/browse/HBASE-24972
             Project: HBase
          Issue Type: Improvement
            Reporter: Sandeep Guggilam
            Assignee: Sandeep Guggilam


{color:#1d1c1d}Creating the connection with ZK  is asynchronous and notified via the passed in watcher about the  successful connection event. When we attempt any operations, we try to create a connection and then perform a read/write ({color}{color:#1d1c1d}[https://github.com/apache/hbase/blob/979edfe72046b2075adcc869c65ae820e6f3ec2d/hbase-zookeeper/src/main/java/org/apache/hadoop/hbase/zookeeper/RecoverableZooKeeper.java#L323]{color}{color:#1d1c1d}) without really waiting for the notification event ([https://github.com/apache/hbase/blob/979edfe72046b2075adcc869c65ae820e6f3ec2d/hbase-zookeeper/src/main/java/org/apache/hadoop/hbase/zookeeper/ZKWatcher.java#L582)]{color}

 

{color:#1d1c1d}it might be possible we get ConnectionLoss errors when we perform operations on ZK without waiting for the connection attempt to succeed{color}
