YunFan Zhou updated YARN-6862: ------------------------------ Comment: was deleted (was: [~jlowe] It is very likely that the process is exists, but the resource usage especially the used CPU is very problematic. I think we should fix it.) > Nodemanager resource usage metrics sometimes are negative > --------------------------------------------------------- > > Key: YARN-6862 > URL: https://issues.apache.org/jira/browse/YARN-6862 > Project: Hadoop YARN > Issue Type: Bug > Components: nodemanager > Affects Versions: 2.8.2 > Reporter: YunFan Zhou > > When we collect real-time metrics of resource usage in NM, we found those > values sometimes are invalid. > For example, the following are values when collected at some point: > "milliVcoresUsed":-5808, > "currentPmemUsage":-1, > "currentVmemUsage":-1, > "cpuUsagePercentPerCore":-968.1026 > "cpuUsageTotalCoresPercentage":-24.202564, > "pmemLimit":2147483648, > "vmemLimit":4509715456 > There are many negative values, there may a bug in NM. > We should fix it, because the real-time metrics of NM is pretty important for > us sometimes. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
