Subject [jira] [Commented] (HADOOP-10512) Document usage of node-group layer topology
Date Sat, 21 Mar 2015 00:45:38 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-10512?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14372399#comment-14372399

Allen Wittenauer commented on HADOOP-10512:

It's kind of dumb at this point waiting years for some other piece that may never materialize.
Clearly people are using the feature and it is complete enough that some documentation should
exist.  Plus HDFS-6261 exists too.

and rack in some situations. We should document it after YARN-18 and YARN-19 is figured out.
