Subject [jira] [Commented] (YARN-2619) NodeManager: Add cgroups support for disk I/O isolation
Date Wed, 29 Apr 2015 13:26:07 GMT

    [ https://issues.apache.org/jira/browse/YARN-2619?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14519342#comment-14519342

Varun Vasudev commented on YARN-2619:

The sharing is just an equal split of disk operations. The number 500 is just arbitrary -
all that matters is that all containers get assigned the same weight which ensures they get
an equal share of disk operations. Once we have scheduling support, the weight will be determined
dynamically based on the allocated resources.
