> 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|https://issues.apache.org/jira/browse/YARN-5464?focusedCommentId=16126119&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-16126119]).
> Once YARN-5464 is done, we can undo this doc change.
