Hello, thank you for your help. We made progress. However, now we are running into an ERROR 500 when we try to POST the filled out template that we exported before. We verified again, that there is no problem with the json format and that there is no typo in the instantiator section. We did following command: # curl -X POST -H "Content-Type: application/json" -d @cloudera.json http://admin:admin@<IP>:7182/api/v54/cm/importClusterTemplate?addRepositories=true Warning: Couldn't read data from file "cloudera.json", this makes an Warning: empty POST. <html> <head> <meta http-equiv="Content-Type" content="text/html;charset=ISO-8859-1"/> <title>Error 500 Error processing POST request.

What can be the cause of this? Thanks for your help!

I try to deploy and configure a CDP cluster over the CM RestAPI. However, I'm running into different problems around this. Starting with where to find values, e.g. /clusters/{clusterName}/parcels/products/{product}/versions/{version} where to find {product} and {version} for that. Or for curl -X POST -u admin:admin -i -H "Content-Type: application/json" -d '{ "items" : [ { "ipAddress" : "{ipAddress1}", "hostname" : "{hostname1}" }, { "ipAddress" : "{ipAddress2}", "hostname" : "{hostname2}" } ] }' http://{cmIpAddress}:7180/api/v54/clusters/{clusterName}/hosts it returns following error although the Rest API documentation claims, that ipAddress is a required attribute HTTP/1.1 400 Bad Request [...] { "message" : "Unrecognized property: 'ipAddress'" } If I use the API Documentation on the CM it also does not fill out the information automatically, which would have been really helpful. So my question: could you provide the steps how to deploy and configure a CDP cluster with the CM Rest API that maps to the steps on the CM UI from the point the CM is installed (so starting with providing the license) up to an up and running cluster? CM version is 7.11.3.7 and CDH is 7.1.9.9. REST API version is v54 based on the internal API documentation of the CM.
