> RetryInovcationHandler uses worthLogging flag to decide if it will do
> logging. worthLogging will be false for first fails over given
> invocationFailoverCount is zero. That addresses the log noise where the
> second-listed NN is active.
> For other failover scenarios, it will be useful to log the error message at
> info level for analysis purpose.
