> ApplicationMasterLauncher create a thread pool whose size is 10 to deal with
> AMLauncherEventType(LAUNCH and CLEANUP).
> In our cluster, there was many NM with 10+ AM running on it, and one shut
> down for some reason. After RM found the NM LOST, it cleaned up AMs running
> on it. Then ApplicationMasterLauncher need handle these 10+ CLEANUP event.
> ApplicationMasterLauncher's thread pool would be filled up, and they all hang
> in the code containerMgrProxy.stopContainers(stopRequest) because NM was
> down, the default RPC time out is 15 mins. It means that in 15 mins
> ApplicationMasterLauncher could not handle new event such as LAUNCH, then new
> attempts will fails to launch because of time out.
