Review comment:
@timmylicheng Thanks for looking at this patch !
Good point !
As far as I know, the failover proxy provider will print out the IP address,
along with the exception.
We need revisit this code in future, when the failover proxy provider should
support leaderHint. I've file a jira to track this task,
https://issues.apache.org/jira/browse/HDDS-4545
