Subject [jira] [Commented] (HBASE-15135) Add metrics for storefile age
Date Wed, 27 Jan 2016 16:44:40 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15135?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15119742#comment-15119742

Sean Busbey commented on HBASE-15135:
-------------------------------------


The build error for module ordering is YETUS-280. you can build with this change in place
if you [go to the precommit job|https://builds.apache.org/view/PreCommit%20Builds/job/PreCommit-HBASE-Build/]
and use "build with parameters" to check the USE_YETUS_PRERELEASE option.

> In order to make sure that compactions are fully up to date it would be nice to have
metrics on:
> * Max storefile age
> * Min storefile age
> * Average storefile age
> * Number of reference files
> If we could have those metrics per region and per regionserver it would be awesome.
