Subject [jira] [Commented] (YARN-18) Configurable Hierarchical Topology for YARN
Date Fri, 22 Aug 2014 01:09:13 GMT

    [ https://issues.apache.org/jira/browse/YARN-18?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14106279#comment-14106279

Junping Du commented on YARN-18:
--------------------------------

Thanks [~gujilangzi] and [~ashahab] for the effort! Last time when I was in a YARN meetup,
the feedback from YARN community is that a hierarchical way is more preferable. So I renew
the proposal here (see newer one attached), but haven't get chance to prototype a patch. Quite
busy recently on other YARN features, so it may take more time for me to have a patch ready.
Let me know if you have interest on helping dev/review/test effort for new patches. Thx!

> Per discussion in the design lounge of Hadoop Summit 2013, we agreed to change the design
of “Pluggable topologies with NodeGroup for YARN” to support a configurable hierarchical
topology that makes adding additional locality layers simple. Please refer attached doc HierachicalTopologyForYARNr1.pdf
for details.
