[jira] [Created] (HDFS-10534) NameNode WebUI should display
DataNode usage rate with a certain percentile
Zhe Zhang created HDFS-10534:
--------------------------------
Summary: NameNode WebUI should display DataNode usage rate with a certain percentile
Key: HDFS-10534
URL: https://issues.apache.org/jira/browse/HDFS-10534
Project: Hadoop HDFS
Issue Type: Improvement
Components: namenode, ui
Reporter: Zhe Zhang
In addition of *Min/Median/Max*, another meaningful metric for cluster balance is DN usage rate at a certain percentile (e.g. 90 or 95). We should add a config option, and another filed on NN WebUI, to display this.
