Aaron T. Myers updated HDFS-2678:
---------------------------------
Attachment: HDFS-2678.patch
Here's a patch which addresses the issue. No tests are included since the patch
is pretty trivial. I tested this manually by starting up a pair of HA NNs and
confirmed that no connection retries occur, only failover retries.
> HA: When a FailoverProxyProvider is used, DFSClient should not retry
> connection ten times before failing over

> Even though the {{FailoverOnNetworkExceptionRetry}} retry policy tries to
> fail over immediately, in the event the active is down, o.a.h.ipc.Client
> (below the RetryPolicy) will retry the initial connection 10 times before
> bubbling up this exception to the RetryPolicy. This should be much quicker.
