      Description

      Server-side NM graceful decom currently does not work correctly when an RM failover occurs because we don't persist the info in the state store (see YARN-5464). Given time constraints for Hadoop 3 beta 1, we've decided to document this limitation and recommend client-side NM graceful decom in the meantime if you need this functionality (see this comment). Once YARN-5464 is done, we can undo this doc change.
