Subject [jira] [Commented] (HADOOP-7734) metrics2 class names inconsistent between trunk and 20x
Date Tue, 11 Oct 2011 21:51:12 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7734?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13125413#comment-13125413

Luke Lu commented on HADOOP-7734:
---------------------------------

bq. can't we backport the improvements into 20x as well? What's the point of having them in
20x if no one can adopt them without breaking in the next version?

Well, backporting to 20x say 206 would break existing plugins in production for previous 20x
releases (203-205 and some previous Y releases). 0.20 to 0.23 is a considered a major release
change and people expect things (especially none end-user facing stuff like metrics) break
a little :) 0.23 already requires major deployment/config changes, of which metrics is a only
a small part.

> The new metrics2 framework was backported into the 20x branch, but the class names differ
between the two branches. So, if anyone were to build against the metrics2 API in 20x, it
would break when they upgraded to 23. We should reconcile the two so that they are API-compatible.
