I was trying to install the hawq plugin on ambari on top of hdp 2.3 and it fails. The command I am using to check the status is
curl -u admin:admin -H X-Requested-By:devops -i -X GET "http://localhost:8080/api/v1/clusters/Sandbox/services/HAWQ?fields=ServiceInfo/state"
And the procedure for creating hawq on hdp is here [link] ( http://blog.pivotal.io/big-data-pivotal/p-o-v/pivotal-hawq-lands-in-the-hortonworks-sandbox). I would be grateful if someone can say what could be the reason for failure
