Yongjun Zhang commented on SPARK-25642: --------------------------------------- Thanks [~pgandhi] . What I observed is most of the time numRegisteredConnections 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. Wonder if anyone else who look at these metrics have different observations. > Add new Metrics in External Shuffle Service to help determine Network > performance and Connection Handling capabilities of the Shuffle Service > --------------------------------------------------------------------------------------------------------------------------------------------- > > Key: SPARK-25642 > URL: https://issues.apache.org/jira/browse/SPARK-25642 > Project: Spark > Issue Type: Improvement > Components: Shuffle, Spark Core > Affects Versions: 2.4.0 > Reporter: Parth Gandhi > Assignee: Parth Gandhi > Priority: Minor > Fix For: 3.0.0 > > > Recently, the ability to expose the metrics for YARN Shuffle Service was > added as part of [SPARK-18364|[https://github.com/apache/spark/pull/22485]]. > We need to add some metrics to be able to determine the number of active > connections as well as open connections to the external shuffle service to > benchmark network and connection issues on large cluster environments. -- This message was sent by Atlassian Jira (v8.20.1#820001) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
