Subject [jira] [Commented] (YARN-469) Make scheduling mode in FS pluggable
Date Mon, 25 Mar 2013 23:27:16 GMT

    [ https://issues.apache.org/jira/browse/YARN-469?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13613298#comment-13613298

Alejandro Abdelnur commented on YARN-469:

+1. Though, there is one naming nit. {{parse(String className)}} s/className/mode/ and the
javadoc should state that mode can be 'fair', 'fifo' or the name of a class implementing {{SchedulingMode}}.

Mind a new patch with this correction?

> Currently, scheduling mode in FS is limited to Fair and FIFO. The code typically has
an if condition at multiple places to determine the correct course of action.
> Making the scheduling mode pluggable helps in simplifying this process, particularly
as we add new modes (DRF in this case).
