Arun C Murthy commented on MAPREDUCE-2803:
------------------------------------------
Luke yarn-site.xml should be read only by servers (RM & NM) ... and clients
only need the RM address which we can separate out later - having multiple
config files to manage makes ops' life much harder. Makes sense?

> yarn-{site,default}.xml contains many knobs none-ops users don't need to know
> (e.g., server principals and keytab locations etc.). It's confusing to users.
> Let's separate the server config into separate files
> yarn-server-{site.default}.xml
> yarn common and client configs would remain in yarn-{site,default}.xml and
> YarnServerConfig shall read both.
