------------------------------------
[~elgoiri] Looking forward to your comments.
> 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. I think that the same ClusterID only needs
> to take one Max and then do the accumulation.
