[jira] [Created] (HADOOP-7928) HA: Client failover policy is incorrectly trying to fail over all IOExceptions

HA: Client failover policy is incorrectly trying to fail over all IOExceptions
------------------------------------------------------------------------------

                 Key: HADOOP-7928
                 URL: https://issues.apache.org/jira/browse/HADOOP-7928
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: ha, ipc
    Affects Versions: HA Branch (HDFS-1623)
            Reporter: Todd Lipcon
            Assignee: Aaron T. Myers
            Priority: Blocker


In the {{FailoverOnNetworkExceptionRetry}} implementation, we're returning FAILOVER_AND_RETRY for any IOException, so long as the call is idempotent. So, for example, {{getFileInfo}} on a file you don't have access to throws AccessControlException which incorrectly triggers a failover. We should not failover on RemoteExceptions unless they are StandbyException.
