Checking cluster services

You must ensure that all services, you installed, are running in your cluster.

Perform one of the following tasks for checking if the cluster services are running:

Manually from the Ambari UI
Run the service check for each service under Service Actions > Run Service Check.

Through Ambari API

curl ${securecurl} -u "${ambariuser}":"${ambaripwd}" -i -H 'X-Requested-By: ambari' -X PUT -d '{"RequestInfo": {"context" :"Start All via REST"}, "Body": {"ServiceInfo": {"state": "STARTED"}}}' ${ambariprotocol}://${ambariserver}:${ambariport}/api/v1/clusters/${clustername}/services/

Restart all services. Check if time service stops and starts:

###STOP
# curl ${securecurl} -u "${ambariuser}":"${ambaripwd}" -i -H 'X-Requested-By: ambari' -X PUT -d '{"RequestInfo": {"context" :"Stop All via REST"}, "Body": {"ServiceInfo": {"state": "INSTALLED"}}}' ${ambariprotocol}://${ambariserver}:${ambariport}/api/v1/clusters/${clustername}/services/
###START (takes a long time)
# curl ${securecurl} -u "${ambariuser}":"${ambaripwd}" -i -H 'X-Requested-By: ambari' -X PUT -d '{"RequestInfo": {"context" :"Start All via REST"}, "Body": {"ServiceInfo": {"state": "STARTED"}}}' ${ambariprotocol}://${ambariserver}:${ambariport}/api/v1/clusters/${clustername}/services/

If any cluster service is not running, fix the service settings before you proceed.
