Subject [jira] [Commented] (YARN-1008) MiniYARNCluster with multiple nodemanagers, all nodes have same key for allocations
Date Sat, 10 Aug 2013 01:23:48 GMT

    [ https://issues.apache.org/jira/browse/YARN-1008?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13735655#comment-13735655
] 

Omkar Vinit Joshi commented on YARN-1008:
-----------------------------------------

[~tucu00] I don't see why we need to change all the NodeId stuff? Can't we simply call toString()
method where ever we need host:port?? why we need new configuration and modification to NodeId?
I see where ever we are using FiCaSchedulerNode.getHostName()..we should replace it with FiCaSchedulerNode.getNodeId().toString()??
thoughts please?

> While the NMs are keyed using the NodeId, the allocation is done based on the hostname.

> This makes the different nodes indistinguishable to the scheduler.
> There should be an option to enabled the host:port instead just port for allocations.
The nodes reported to the AM should report the 'key' (host or host:port).
