[jira] [Created] (HADOOP-17116) Skip Retry INFO logging on first failover from a proxy

Hanisha Koneru created HADOOP-17116:
---------------------------------------

             Summary: Skip Retry INFO logging on first failover from a proxy
                 Key: HADOOP-17116
                 URL: https://issues.apache.org/jira/browse/HADOOP-17116
             Project: Hadoop Common
          Issue Type: Task
            Reporter: Hanisha Koneru
            Assignee: Hanisha Koneru


RetryInvocationHandler logs an INFO level message on every failover except the first. This used to be ideal before when there were only 2 proxies in the FailoverProxyProvider. But if there are more than 2 proxies (as is possible with 3 or more NNs in HA), then there could be more than one failover to find the currently active proxy.

To avoid creating noise in clients logs/ console, RetryInvocationHandler should skip logging once for each proxy.
