> I had 2 config-groups which overrode the same config
> ({{yarn.nodemanager.log.retain-second}}). Now from the manage-config-groups
> dialog I removed the host from one config-group, and added it in the other
> config-group. Then I hit Save.
> YARN correctly said that 1 host needs restarts. I clicked on the 'Stop
> Components' button and it correctly stopped the NodeManager component.
> However the 'Start Components' button is not enabled. Refreshing etc. does
> not help either.
