Subject [jira] [Commented] (YARN-2139) Add support for disk IO isolation/scheduling for containers
Date Tue, 10 Jun 2014 20:17:03 GMT

    [ https://issues.apache.org/jira/browse/YARN-2139?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14026935#comment-14026935

Wei Yan commented on YARN-2139:

For the disk IO, we can use cgroup to limit the IO usage for each local container. For HDFS
remote read/write, may refer as the network IO. We can also limit the network bandwidth for
each container (YARN-2140).
bq. Otherwise, you could perhaps include some IO requirements in a container request (light,
medium, heavy) and include that in placement
Yes, put some fields in the container request is good. This can help avoid put two IO-intensive
tasks together.
