>
> In flip6, for flink on yarn mode, RM requests container from yarn according
> to the requirement of the JM. But the AMRMClientAsync used in yarn doesn't
> guarantee that the number of containers returned exactly equal to the number
> requested. So it need to record the number request by flink rm and return the
> redundant ones to yarn.
