Some operations of FsDatasetImpl need to hold Lock, and sometimes it costs long time to execute since it include IO operation in Lock. I propose to add metrics for this operations then it could be more convenient for monitor and dig bottleneck. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
