[jira] [Commented] (YARN-2139) Add support for disk IO isolation/scheduling for containers

    [ https://issues.apache.org/jira/browse/YARN-2139?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14049758#comment-14049758 ] 

Steve Loughran commented on YARN-2139:
--------------------------------------

looks a good first draft
# unless this does address HDFS, call out that this is local disk IO
# this is really disk io bandwidth, so it should use an option, like vlocaldiskIObandwidth. This will avoid confusion (make clear its not HDFS), and add scope for the addition of future options: IOPs and actual allocation of entire disks to containers
# what's the testability of this feature?
