> This problem appears for that the function startRegistrationTimeout in 
> TaskExecutor.java is executed in multiple places.
> In the function start, it will be executed by 
> resourceManagerLeaderRetriever.start(new ResourceManagerLeaderListener()) in 
> async way. Also, it will be executed in the end of the start function. The 
> order of these two executions is not guaranteed but they will change the same 
> variable currentRegistrationTimeoutId. If the async way is fast enough to 
> execute startRegistrationTimeout() first. It will fail 5 minutes later for 
> the startRegistrationTimeout's execution in the end of the start function.
> The solution is to put the function startRegistrationTimeout in the start 
> function before resourceManagerLeaderRetriever.start() . After doing this, 
> the problem never appears again.
