Subject [jira] [Commented] (YARN-1462) AHS API and other AHS changes to handle tags for completed MR jobs
Date Tue, 02 Jun 2015 19:56:50 GMT

    [ https://issues.apache.org/jira/browse/YARN-1462?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14569648#comment-14569648
] 

Siddharth Seth commented on YARN-1462:
--------------------------------------

ApplicationReport.newInstance is used by mapreduce and Tez, and potentially other applications
which may be modeled along the same AMs. It'll be useful to make the API change here compatible.
This is along the lines of newInstances being used for various constructs like ContainerId,
AppId, etc.
With the change, I don't believe MR2.6 will work with a 2.8 cluster - depending on how the
classpath is setup.
