Hitesh Shah commented on YARN-2375: ----------------------------------- bq. Do you mean the semantic incompatible? Semantic or not - it looks to be an incompatible change as you are expecting applications to change to be able to use Timeline "correctly". bq. It sounds reasonable. Does it break any depending project? Yes it does break things. You are now expecting all downstream projects to change in terms of how to use the TimelineClient and the fact that they also now need to inspect the value of a YARN config property. Changing distributed-shell should have been a red-flag from a compatibility point of view. Agreed that the change is reasonable but you cannot make changes like these in a patch release. > Allow enabling/disabling timeline server per framework > ------------------------------------------------------ > > Key: YARN-2375 > URL: https://issues.apache.org/jira/browse/YARN-2375 > Project: Hadoop YARN > Issue Type: Sub-task > Reporter: Jonathan Eagles > Assignee: Mit Desai > Fix For: 2.7.0, 2.6.1 > > Attachments: YARN-2375.1.patch, YARN-2375.patch, YARN-2375.patch, > YARN-2375.patch, YARN-2375.patch > > > This JIRA is to remove the ats enabled flag check within the > TimelineClientImpl.
