Subject [jira] [Commented] (YARN-1474) Make schedulers services
Date Sat, 10 May 2014 22:06:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-1474?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13992559#comment-13992559
] 

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

Updated a patch to remove unnecessary synchronization. Maybe findbugs warn this patch, because
the field {{applications}} is not only non-final but also un-synchronized. Maybe I can explain
why it can be un-synchronized. How about using {{edu.umd.cs.findbugs.annotations.SuppressWarnings}}
such methods? 

Anyway, let's waiting for Jenkins.

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