Subject [jira] [Commented] (HDFS-11468) Ozone: SCM: Add Node Metrics for SCM
Date Wed, 25 Oct 2017 02:56:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-11468?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16218016#comment-16218016

Xiaoyu Yao commented on HDFS-11468:

Thanks [~linyiqun] for the contribution and [~cheersyang] for the review. My late +1 for the
latest patch is here. 

Once, HDFS-12474 is in, we will move the current metrics update code from StorageContainerManager#sendContainerReport
into the container handler. 

Also, 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 work can all be handled in follow up JIRAs.
