[jira] [Created] (HDFS-6477) Have RetryInvocationHandler log failover attempt at INFO level

Ming Ma created HDFS-6477:
-----------------------------

             Summary: Have RetryInvocationHandler log failover attempt at INFO level
                 Key: HDFS-6477
                 URL: https://issues.apache.org/jira/browse/HDFS-6477
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Ming Ma


RetryInovcationHandler uses worthLogging flag to decide if it will do logging. worthLogging will be false for first fails over given invocationFailoverCount is zero. That addresses the log noise where the second-listed NN is active.

For other failover scenarios, it will be useful to log the error message at info level for analysis purpose.
