[jira] [Commented] (HADOOP-12622) RetryPolicies (other than
FailoverOnNetworkExceptionRetry) should put on retry failed reason or the
log from RMProxy's retry could be very misleading.

> It actually only log client side retry on NetworkConnection failure but not include any info on RetryInvocationHandler where the real retry policy works. From the code below in RetryInvocationHandler.java, even the retry ends, we don't put warn messages to include how much/many time/ counts we spent on retry logic that make it harder to debug.
> {code}
> if (failAction != null) {
> if (failAction.reason != null) {
> LOG.warn("Exception while invoking " + currentProxy.proxy.getClass()
> + "." + method.getName() + " over " + currentProxy.proxyInfo
> + ". Not retrying because " + failAction.reason, ex);
> }
> throw ex;
> }
> {code}
> We should add failAction.reason as much as we can in multiple retry policies. In addition, we should keep consistent in log level for message during the retry attempts: now the ipc.client is INFO, but RetryInvocationHandler is DEBUG (if not fail_over). We should keep them consistent or it could be very confusing.
