Subject [jira] [Commented] (HBASE-15135) Add metrics for storefile age
Date Thu, 28 Jan 2016 15:24:39 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15135?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15121684#comment-15121684
] 

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

It's this section:

{code}
    ## from github
    curl -L https://api.github.com/repos/apache/yetus/tarball/HEAD > yetus.tar.gz
    tar xvpf yetus.tar.gz
{code}

it must have been the github outage yesterday. looks like curl won't fail on HTTP 4xx or 5xx
unless we tell it to via {{--fail}}. I'll update the job to do this.

> 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.
