In ambari version AMBARI-2.5.1.7 we needed to do another step after recommissioning steps above mentioned. The nodemanger was going to stopped state after the recommissioning call. Needed to change the state from installed to started. curl -u user:pass -i -H 'X-Requested-By: ambari' -X PUT -d '{"HostRoles": {"state": "STARTED"}}' http://{$ambari_master_host}:{$ambari_master_port}/api/v1/clusters/{$clustername}hosts/{$host}/host_components/NODEMANAGER; Same steps are followed by the ambari server when doing the recommission.
