Subject [jira] [Updated] (HDFS-12787) Ozone: SCM: Aggregate the metrics from all the container reports
Date Fri, 10 Nov 2017 07:17:00 GMT

     [ https://issues.apache.org/jira/browse/HDFS-12787?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Yiqun Lin updated HDFS-12787:
    Attachment: HDFS-12787-HDFS-7240.002.patch

Revisit this again. There is one case we should concern: Sometimes one node may become stale/dead
node, then we should remove its  container report in global view metrics.
Attach the new patch for addressing this case.

> We should aggregate the metrics from all the reports of different datanodes in addition
to the last report. This way, we can get a global view of the container I/Os over the ozone
cluster. This is a follow up work of HDFS-11468.
