J.Andreina updated HDFS-8670: ----------------------------- Attachment: HDFS-8670.3.patch > Better to exclude decommissioned nodes for namenode NodeUsage JMX > ----------------------------------------------------------------- > > Key: HDFS-8670 > URL: https://issues.apache.org/jira/browse/HDFS-8670 > Project: Hadoop HDFS > Issue Type: Bug > Reporter: Ming Ma > Assignee: J.Andreina > Attachments: HDFS-8670.1.patch, HDFS-8670.2.patch, HDFS-8670.3.patch > > > The namenode NodeUsage JMX has Max, Median, Min and Standard Deviation of > DataNodes usage, it currently includes decommissioned nodes for the > calculation. However, given balancer doesn't work on decommissioned nodes and > sometimes we could have nodes stay in decommissioned states for a long time; > it might be better to exclude decommissioned nodes for the metrics > calculation. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
