Alejandro Abdelnur updated YARN-1008:
-------------------------------------
Attachment: YARN-1008.patch
new patch that undoes changes from PB and public API.
The changes are in the scheduler only to use or not the port as part of then
node name for matching purposes. Renamed {{SchedulerNode#getHostName()}} method
to {{SchedulerNode#getNodeName()}} and added comment explaining when hostname
or hostname:port is to be used.
> MiniYARNCluster with multiple nodemanagers, all nodes have same key for
> allocations

> 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).
