Subject [jira] [Commented] (YARN-3176) In Fair Scheduler, child queue should inherit maxApp from its parent
Date Tue, 04 Aug 2015 04:25:05 GMT

    [ https://issues.apache.org/jira/browse/YARN-3176?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14653038#comment-14653038

Karthik Kambatla commented on YARN-3176:
----------------------------------------

The patch looks reasonable. I forget where exactly, but we do have code that figures out parent
queue for a queue that does things similar to what the patch adds. Can we please check that
and avoid duplication if possible. 

[~asuresh] - does the patch look reasonable to you?

> if the child queue does not have a maxRunningApp limit, it will use the queueMaxAppsDefault.
This behavior is not quite right, since queueMaxAppsDefault is normally a small number, whereas
some parent queues do have maxRunningApp set to be more than the default
