Subject [jira] [Commented] (YARN-1474) Make schedulers services
Date Tue, 06 May 2014 17:27:15 GMT

    [ https://issues.apache.org/jira/browse/YARN-1474?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13990855#comment-13990855

Tsuyoshi OZAWA commented on YARN-1474:
--------------------------------------

> Updated a patch to synchronize Scheduler related methods correctly. 
Removed @Lock(Lock.NoLock.class) from CapacityScheduler#getApplicationAttempt() because the
method is made synchronized.

I found this is bad solution. I'll update a patch today.

> Schedulers currently have a reinitialize but no start and stop.  Fitting them into the
YARN service model would make things more coherent.
