Yongjun Zhang commented on SPARK-31646:
---------------------------------------
Thanks [~mauzhang] What I observed is most of the time
numRegisteredConenctions is smaller than numActiveConnections.
For example, in one case the gap can be as large as beyond 3k. while
numRegisteredConnections range between 0 - 2.5k, and
numActiveRegisteredConnections range between 0 - 3.6k.
> Remove unused registeredConnections counter from ShuffleMetrics
