Daniel Templeton commented on YARN-4413:
----------------------------------------
[~kshukla], this patch is more for the UI. The point is that if I
decommission, shutdown, and then recommission a node, the UI will continue to
show it as decommissioned until the node is restarted. This patch closes that
gap.
> Nodes in the includes list should not be listed as decommissioned in the UI

> If I decommission a node and then move it from the excludes list back to the
> includes list, but I don't restart the node, the node will still be listed by
> the web UI as decomissioned until either the NM or RM is restarted. Ideally,
> removing the node from the excludes list and putting it back into the
> includes list should cause the node to be reported as shutdown instead.
