Describe the bug

The connection between the client and shufflerserver is not closed. As a result, the maptask container does not exit.
1.map container does not exit when reduce is running
2.When cluster resources are used up and some maps are not allocated, am waits for a one-minute timeout, kills the completed map container, and allocates resources to other maps

error log like:
2023-03-11 02:42:16,826 INFO [Ping Checker] org.apache.hadoop.yarn.util.AbstractLivelinessMonitor: Expired:attempt_1676901654399_1531374_m_000190_0 Timed out after 60 secs

In the close method of the RssMapOutputCollector, closing the shuffle client solves this problem
