> org.apache.hadoop.yarn.server.resourcemanager.TestRMRestart.testQueueMetricsOnRMRestart fails randomly because of a race condition.
> The test validates that metrics are incremented, but does not wait for all transitions to finish before checking for the values.
> It also resets metrics after kicking off recovery of second RM. The metrics that need to be incremented race with this reset causing test to fail randomly.
> We need to wait for the right transitions.
