----------------------------------
Summary: 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
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.
