You are partially incorrect - NameNode is not an SPOF any longer in
2.x releases. Please look at the docs that cover HA in the release you
use, such as http://hadoop.apache.org/docs/current/hadoop-yarn/hadoop-yarn-site/HDFSHighAvailabilityWithQJM.html.
RM HA is not yet present, but is incoming. See YARN-149 for the
ongoing design discussions.
