[ https://issues.apache.org/jira/browse/HDFS-16039?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=17351332#comment-17351332 ] Íñigo Goiri commented on HDFS-16039: I remember there was some other JIRA that tried to avoid the double counting of DNs. Maybe we can check the total list of DNs that is correct, and extract the info from there. > RBF: Some indicators of RBFMetrics count inaccurately > -- > > Key: HDFS-16039 > URL: https://issues.apache.org/jira/browse/HDFS-16039 > Project: Hadoop HDFS > Issue Type: Bug > Components: rbf >Affects Versions: 3.4.0 >Reporter: Xiangyi Zhu >Assignee: Xiangyi Zhu >Priority: Major > > RBFMetrics#getNumLiveNodes, getNumNamenodes, getTotalCapacity > The current statistical algorithm is to accumulate all Nn indicators, which > will lead to inaccurate counting.
