Description

RetryInvocationHandler logs an INFO level message on every failover except the first. This used to be ideal before when there were only 2 proxies in the FailoverProxyProvider. But if there are more than 2 proxies (as is possible with 3 or more NNs in HA), then there could be more than one failover to find the currently active proxy.

To avoid creating noise in clients logs/ console, RetryInvocationHandler should skip logging once for each proxy.
