Subject [jira] [Commented] (YARN-1311) Fix app specific scheduler-events' names to be app-attempt based
Date Fri, 13 Dec 2013 15:57:08 GMT

    [ https://issues.apache.org/jira/browse/YARN-1311?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13847594#comment-13847594

Jason Lowe commented on YARN-1311:
----------------------------------

The branch-2 build is broken, and it seems to be related to this change:

{noformat}
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.5.1:compile
(default-compile) on project hadoop-sls: Compilation failure: Compilation failure:

It appears a similar compilation failure was fixed on trunk, but branch-2 is still failing.

> Today, APP_ADDED and APP_REMOVED are sent to the scheduler. They are misnomers as schedulers
only deal with AppAttempts today. This JIRA is for fixing their names so that we can add App-level
events in the near future, notably for work-preserving RM-restart.
