Subject [jira] [Commented] (YARN-2139) Add support for disk IO isolation/scheduling for containers
Date Wed, 11 Jun 2014 03:55:02 GMT

    [ https://issues.apache.org/jira/browse/YARN-2139?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14027379#comment-14027379
] 

Alejandro Abdelnur commented on YARN-2139:
------------------------------------------

As Sandy says, for local reads short circuit kicks in for local HDFS blocks. It kicks in for
any other local FS access. So block io controller would kick in. For remote HDFS reads, network
io controller would kick in. So effectively we can control the resources the container uses.
