Bikas Saha commented on YARN-1660:
----------------------------------
Its great that we are making these ease of use changes. But unfortunately,
there are no comments/javadoc/example configuration in the defaults files that
is showing people how they can go about easily configuring their RM's in
different ways. I can try to read the code carefully and experiment with
configs to figure things out, but right now its not clear to me what is the
minimal config I can use to get started. On the other side of the spectrum, can
I specify the exact hostname and port for every service? Do I have to suffix it
with RM id? Can I specify some specific ports and leave the remaining
hostname/ports to be filled in by the RM? Do I need to suffix those with RM id?
I am sure this is common knowledge among the folks working on this but that may
not hold for everyone. Or it may just be that I am slow in understanding stuff
this morning :P

> Currently the user has to specify all the various host:port properties for
> RM. We should follow the pattern that we do for non HA setup where we can
> specify yarn.resourcemanager.hostname.rm-id and the defaults are used for all
> other affected properties.
