AMBARI REST API to start all the services on an individual node

krish2 — Tue, 22 Nov 2016 03:51:56 GMT

Hi, I have a 50+ node HDP 2.3 cluster. It so happened that one of the nodes restarted and all the services installed on that node were stopped. Is there a way, a rest api call that I can use to start all the services just on this one particular node

This should work

curl -u admin:admin -H "X-Requested-By:ambari" -X PUT -d '{"HostRoles": {"state": "STARTED"}}' http://AMBARI_HOST:8080/api/v1/clusters/CLUSTER_NAME/hosts/HOST_ON_WHICH_COMPONENTS_NEED_TO_BE_STARTED/host_components/

Components in Maintenance mode will be ignored.

This helped a lot thank you. I was able to run this call from the command line and start the services on this node.
