Xuan Gong commented on YARN-1660:
---------------------------------
bq. 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.
Yes, we need to add that.
bq. 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?
Yes, we can specify the exact hostname and port for every services or any of
them. If we do that, we need to suffix them with RM id. Also, if we do the
specify, the rm will read the specified hostname and port instead of the
default ones.
> add the ability to set yarn.resourcemanager.hostname.rm-id instead of setting
> all the various host:port properties for RM

> 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.
