> Currently, if RM work preserving restart happens while distributed shell is 
> running, distribute shell AM may re-launch all the containers, including 
> new/running/complete. We must make sure it won't re-launch the 
> running/complete containers.
> We need to remove allocated containers from 
> AMRMClientImpl#remoteRequestsTable once AM receive them from RM.
