jerryshao 1da5822e6a [SPARK-21934][CORE] Expose Shuffle Netty memory usage to MetricsSystem ... ## What changes were proposed in this pull request? This is a followup work of SPARK-9104 to expose the Netty memory usage to MetricsSystem. Current the shuffle Netty memory usage of `NettyBlockTransferService` will be exposed, if using external shuffle, then the Netty memory usage of `ExternalShuffleClient` and `ExternalShuffleService` will be exposed instead. Currently I don't expose Netty memory usage of `YarnShuffleService`, because `YarnShuffleService` doesn't have `MetricsSystem` itself, and is better to connect to Hadoop's MetricsSystem. ## How was this patch tested? Manually verified in local cluster. Author: jerryshao <sshao@hortonworks.com> Closes #19160 from jerryshao/SPARK-21934.		2017-09-21 13:54:30 +08:00
