Issue Time Tracking ------------------- Worklog Id: (was: 773066) Time Spent: 1h (was: 50m) > Expose aggregate latency of slow node as perceived by the reporting node > ------------------------------------------------------------------------ > > Key: HDFS-16582 > URL: https://issues.apache.org/jira/browse/HDFS-16582 > Project: Hadoop HDFS > Issue Type: New Feature > Reporter: Viraj Jasani > Assignee: Viraj Jasani > Priority: Major > Labels: pull-request-available > Time Spent: 1h > Remaining Estimate: 0h > > When any datanode is reported to be slower by another node, we expose the > slow node as well as the reporting nodes list for the slow node. However, we > don't provide latency numbers of the slownode as reported by the reporting > node. Having the latency exposed in the metrics would be really helpful for > operators to keep a track of how far behind a given slow node is performing > compared to the rest of the nodes in the cluster. > The operator should be able to gather aggregated latencies of all slow nodes > with their reporting nodes in Namenode metrics. -- This message was sent by Atlassian Jira (v8.20.7#820007) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
