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. > AHS API and other AHS changes to handle tags for completed MR jobs > ------------------------------------------------------------------ > > Key: YARN-1462 > URL: https://issues.apache.org/jira/browse/YARN-1462 > Project: Hadoop YARN > Issue Type: Sub-task > Affects Versions: 2.2.0 > Reporter: Karthik Kambatla > Assignee: Xuan Gong > Fix For: 2.8.0 > > Attachments: YARN-1462-branch-2.7-1.2.patch, > YARN-1462-branch-2.7-1.patch, YARN-1462.1.patch, YARN-1462.2.patch, > YARN-1462.3.patch > > > AHS related work for tags. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
