Siqi Li commented on YARN-1415:
-------------------------------
According to the tests in TestQueueMetric.java, AvailableMB is never deducted
when allocating memory to applications. It actually means the total available
memory of the cluster. Therefore, totalMB displayed in the UI should only
include AvailableMB.
> In scheduler UI, including used memory in "Memory Total" seems to be
> inaccurate

>
> "Memory Total" is currently a sum of availableMB, allocatedMB, and
> reservedMB.
> It seems that the term "availableMB" actually means "total memory", since it
> doesn't get decreased when some jobs use a certain amount of memory.
> Hence, the Memory Total should not include allocatedMB, or availableMB
> doesn't get updated properly.
