> In YARN-4901 one of the scheduler tests failed. This seems to be linked to 
> the changes around the placement rules introduced in YARN-8967.
> Applications submitted in the tests are accepted and rejected at the same 
> time:
> {code}
> 2019-04-01 12:00:57,269 INFO  [main] fair.FairScheduler 
> (FairScheduler.java:addApplication(540)) - Accepted application 
> application_0_0001 from user: user1, in queue: root.user1, currently num of 
> applications: 1
> 2019-04-01 12:00:57,269 INFO  [AsyncDispatcher event handler] 
> fair.FairScheduler (FairScheduler.java:rejectApplicationWithMessage(1344)) - 
> Reject application application_0_0001 submitted by user user1 application 
> rejected by placement rules.
> {code}
> This should never happen and is most likely due to the way the tests 
> generates the application and events.
