Alejandro Abdelnur commented on YARN-1343:
------------------------------------------
The problem is that the RMNodeImpl.AddNodeTransition() is not dispatching a
NodesListManagerEventType.NODE_USABLE event to the NodeListManager. Plus, the
NodeListManager handle() for NODE_UNUSABLE should dispatch
RMAppNodeUpdateType.NODE_USABLE events to the apps even if the node was not in
the unusable list.
> NodeManagers additions/restarts are not reported as node updates in
> AllocateResponse responses to AMs
