> As per my understanding following 2 issues causes the issue.
> * WebApp holds the reference to First applicationMasterServer instance, which has rmcontext
with ActiveServiceContext (holds RMApps + nodes map). WebApp remains to life time of RM process.
> * On transistion to active RMNMInfo object is registered inĀ  MBean and never unregistered
on transitionToStandBy
> On transistion to Standby and again based to active new RMContext gets created, but above
2 issues causes first RMcontext persist still RMShutdown.
