{code}
When I use YarnClient.getApplications() to get all applications of RM,
Occasionally, it throw a NPE problem.
{code:java}
RMAppAttempt currentAttempt = rmContext.getRMApps()
.get(attemptId.getApplicationId()).getCurrentAppAttempt();
{code}
if the application id is not in ConcurrentMap<ApplicationId, RMApp>
getRMApps(), it may throw NPE problem.
Can [-YARN-6102-|https://issues.apache.org/jira/browse/YARN-6102] solve this
problem ?
