Siqi Li updated YARN-1415:
--------------------------
Description:
"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.
> In scheduler UI, including used memory in "Memory Total" seems to be
> inaccurate
