Gergely Novák updated YARN-4954:
--------------------------------
    Description: 
TestYarnClient.testReservationAPIs sometimes fails with this error:
{noformat}
java.lang.AssertionError: org.apache.hadoop.yarn.server.resourcemanager.reservation.exceptions.PlanningException:
The request cannot be satisfied
	at org.apache.hadoop.yarn.ipc.RPCUtil.getRemoteException(RPCUtil.java:38)

This is caused by really not having enough available memory to complete the reservation (4
* 1024 MB). In my opinion lowering the required memory (either by lowering the number of containers
to 2, or the memory to 512 MB) would make the test more stable.
