Subject [jira] [Commented] (YARN-5799) Fix OpportunisticAllocation to set the correct value of Node Http Address
Date Fri, 28 Oct 2016 21:20:58 GMT

    [ https://issues.apache.org/jira/browse/YARN-5799?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15616625#comment-15616625
] 

Arun Suresh commented on YARN-5799:
-----------------------------------

Currently, the OpportunisticAllocator uses the NodeId to populate Node relevant information
in the returned Container. Unfortunately, this is not sufficient, as the NodeId does not include
the Http Address (which is the used in the Web UI to redirect to the Node), which is found
only in the {{RMNode}}.

I propose to create a {{RemoteNode}} structure that wraps the NodeId and also includes the
Http Address. Also this new structure should be placed in the {{yarn_server_common_service_protos.proto}}
file, to ensure it is not a public facing API and used only in communication between NM and
RM.

> This proposes to fix the the OpportunisticAllocator, used to allocate OPPORTUNISTIC containers
(both Centrally as well as in a Distributed manner) to correctly populate the Node Http Address
in the returned Container.
