HI, YARN Graceful decommission will wait for jobs to complete. You can pass the timeout value so that YARN will start decommission after x seconds. If no jobs running within x secs then automatically YARN will start decommission without waiting for timeout to happen. CM -> Clusters -> yarn -> Configuration -> In search bar ( yarn.resourcemanager.nodemanager-graceful-decommission-timeout-secs) Set the value and save the configuration and do restart to deploy configs. To decommission a specific host/more hosts  CM -> Clusters -> yarn -> Instances (Select the hosts that you want to decommission) Click -> Actions for selected hosts -> Decommission  In case you want to decommission all the roles of a host then follow this doc  https://docs.cloudera.com/documentation/enterprise/6/6.3/topics/cm_mc_host_maint.html#decomm_host Make sure to mark the answer as the accepted solution.
