Akira AJISAKA updated YARN-1156:
--------------------------------
Description: AllocatedGB and AvailableGB metrics are now integer type. If
there are four times 500MB memory allocation to container, AllocatedGB is
incremented four times by {{(int)500/1024}}, which means 0. That is, the memory
size allocated is actually 2000MB, but the metrics shows 0GB. Let's use float
type for these metrics. (was: AllocatedGB and AvailableGB metrics are now
integer type. If there are four times 500MB memory allocation to container,
AllocatedGB is incremented four times by {{(int)500/1024}}, which means 0. That
is, the memory size allocated is actually 2000MB, but the metrics shows 0GB.
Let's use long type for these metrics.)
