Subject [jira] [Commented] (HDFS-12228) [SPS]: Add storage policy satisfier related metrics
Date Tue, 01 Aug 2017 00:39:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-12228?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16108212#comment-16108212

Uma Maheswara Rao G commented on HDFS-12228:

Please consider [~eddyxu] suggestions below.
And since this call essentially triggers a large async background task, should we put some
logs here? Similarly, it'd be nice to have related JMX stats and some indications in web UI,
to be easier to integrate with other systems.

I think logs can be improved even before merge. [~eddyxu], could you point us where you looking
to ad more logging?
