Subject [jira] [Commented] (YARN-1462) AHS API and other AHS changes to handle tags for completed MR jobs
Date Tue, 02 Jun 2015 02:56:18 GMT

    [ https://issues.apache.org/jira/browse/YARN-1462?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14568433#comment-14568433

Zhijie Shen commented on YARN-1462:

bq. This commit changes newInstance API, breaking Tez build.

{{newInstance}} is marked as \@Private, and it's not supposed to be used ouside Hadoop. What's
the use case in Tez?

bq. is it possible to preserve both versions of the method?

It's possible, but the problem is whether should do it. Theoretically, compatibility is not
required for the private method. If it has strong use case to let app report be created outside
Hadoop, we should mark this method \@Public and keep it compatible over releases.
