[jira] [Commented] (YARN-2298) Move TimelineClient to yarn-common

["Junping Du (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/YARN-2298?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14087087#comment-14087087 ] 

Junping Du commented on YARN-2298:
----------------------------------

Agree that cyclic dependencies between projects are disallowed, otherwise Maven doesn't know which project to build first. From what I know, the only way is to move the related code to somewhere else with several options: move it to a separated project, move it to RM or move it to some common place that both RM and client depend on. I would also prefer the third option just like [~zjshen]'s patch here as previous two options make no sense to me. 
+1. Patch looks good to me. [~jianhe], do you have better way to handle it or additional comments? If not, I will go ahead to commit it later.

> To allow RM to reuse the timeline client code, we have to move it out of yarn-client module, due to maven dependency issues.
