zhihai xu commented on YARN-4201:
---------------------------------
Thanks for the new patch [~hex108], I think it will be better to check
{{scheduler.getSchedulerNode(nodeId)}} not null to avoid NPE.
If {{scheduler.getSchedulerNode(nodeId)}} return null, it means the blacklisted
node is just removed from scheduler, I think it will be ok to not add a removed
node to black List.

> For minicluster (scheduler.include-port-in-node-name is set to TRUE),
> AMBlacklist does not work. It is because RM just puts host to AMBlacklist
> whether scheduler.include-port-in-node-name is set or not. In fact RM should
> put "host + port" to AMBlacklist when it is set.
