> The current _ShuffleMaster_ has an unclear lifecycle which is inconsistent with the _ShuffleEnvironment_ at the _TM_ side. Besides, it is hard to Implement some important capabilities for remote shuffle service. For example, 1) release external resources when a job finished; 2) Stop or start tracking some partitions depending on the status of the external service or system.
> We drafted a document[1] which proposed some simple changes to solve these issues. The document is still not wholly completed yet. We will start a discussion once it is finished.
