Benoy Antony commented on HADOOP-9421:
--------------------------------------

Luke, Is there a sufficient need to add a new state REINITIATE ? The only 
benefit is that it avoids a isSupportedInitiate() call.

>From what I understood, Luke's change is a desirable optimization of Daryn's 
>protocol. Such optimization is quite common in protocols. I agree that it 
>complicates the design a bit. Tt may never be used with the subsequent changes 
>related to IP Failover etc, but why not keep it there as it should not cause 
>any impact on performance?  Why would it cause change in performance ?
