Omkar Vinit Joshi commented on YARN-1350:
-----------------------------------------
[~sinchii] I have basic question..why your nodeId is changing everytime? have
you configured your nodemanager with ephemeral port (0) ? what is NM_ADDRESS?
RM will consider this as same node only when your newly restarted node manager
reports with same node id .. i.e. <host-name>:<port>
> Should not add Lost Node by NodeManager reboot

> Key: YARN-1350
> URL: https://issues.apache.org/jira/browse/YARN-1350
> Project: Hadoop YARN
> Issue Type: Bug
> Components: nodemanager
> Affects Versions: 3.0.0
> Reporter: Shinichi Yamashita
> Attachments: NodeState.txt
>
>
> In current trunk, when NodeManager reboots, the node information before the
> reboot is treated as "LOST".
> This occurs to confirm only Inactive node information at the time of reboot.
> Therefore Lost Node will exist even if NodeManager works in all nodes.
> We should change it not to register Lost Node by the NodeManager reboot.
