Subject [jira] [Commented] (YARN-3318) Create Initial OrderingPolicy Framework and FifoOrderingPolicy
Date Mon, 13 Apr 2015 06:11:13 GMT

    [ https://issues.apache.org/jira/browse/YARN-3318?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14491959#comment-14491959
] 

Craig Welch commented on YARN-3318:
-----------------------------------

added comments to compoundcomparator, re-introduced getId (in lieu of getName), switched to
ResourceUsage - to avoid unnecessary dependency on [YARN-3361] SchedularApplicationAttempt
manages pending in a way it won't have to long term, this doesn't effect the api and allows
these to be committed in any order.  Sticking with "Scheduling" instead of "Cached" as suggested
earlier by [~vinodkv] to keep it's purpose clear (Cached is too general) and because it can't
be used as a generalized "cache" of the values, the lifecycle is tied to use by OrderingPolicies.
