> This is the scenario
> Consider a case where the balancer is going on thus trying to close regions in a RS.
> Before we could close a master switch happens.  
> On Master switch the set of nodes that are in RIT is collected and we first get Data and start watching the node
> After that the node data is added into RIT.
> Now by this time (before adding to RIT) if the RS to which close was called does a transition in AM.handleRegion() we miss the handling saying RIT state was null.
