Viraj Jasani created HDFS-16582: ----------------------------------- Summary: 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
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-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
