Chris Nauroth created HDFS-11063: ------------------------------------ Summary: Set NameNode RPC server handler thread name with more descriptive information about the RPC call. Key: HDFS-11063 URL: https://issues.apache.org/jira/browse/HDFS-11063 Project: Hadoop HDFS Issue Type: Improvement Components: namenode Reporter: Chris Nauroth
We often run {{jstack}} on a NameNode process as a troubleshooting step if it is suffering high load or appears to be hanging. By reading the stack trace, we can identify if a caller is blocked inside an expensive operation. This would be even more helpful if we updated the RPC server handler thread name with more descriptive information about the RPC call. This could include the calling user, the called RPC method, and the most significant argument to that method (most likely the path). -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
