Jonathan Eagles updated YARN-1419:
----------------------------------
Attachment: YARN-1419.patch
Instead of heavily changing the QueueMetrics class and its use of static class
variables and it not unregistering the beans, I've chosen to take a simpler
approach of just measuring the apps submitted delta.
> TestFifoScheduler.testAppAttemptMetrics fails intermittently under jdk7

> QueueMetrics holds its data in a static variable causing metrics to bleed
> over from test to test. clearQueueMetrics is to be called for tests that need
> to measure metrics correctly for a single test. jdk7 comes into play since
> tests are run out of order, and in the case make the metrics unreliable.
