> I was trying out the latest commit of FGS, here is what I am facing.
> When I launch the RM, I need to specify the
> -Dyarn.resourcemanager.hostname=<hostnameOfRM>
> When I did not specify this during RM launch, and try to Flex up.
> NodeManagers may get launched on nodes not running the RM. In this case, the
> NM does not recognize the RM, it tries to look for RM running on the same
> machine. Once such an NM gets launched I am unable to Flex it down, gets hung
> in the same state and end up manually killing it.
> We need a fall-back mechanism to identify the RM incase the hostname is not
> specified, to avoid this situation.
