> In “the real world” large Hadoop clusters will always have hosts that are down, unavailable,
or experiencing transient failures.  Robust, mature, recovery-oriented distributed systems
such as Ambari should always recover from these transient failures automatically without human
intervention (zero touch).  Consider polling periodically for missing nodes that were not
set up initially and adding them as they appear.
