----------------------------------------

             Summary: CLONE - Enhance ERROR returned in case of incorrect  Mpack Version passed during Mpack Advisor call. 
                 Key: AMBARI-24030
                 URL: https://issues.apache.org/jira/browse/AMBARI-24030
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
            Reporter: Swapan Shridhar
            Assignee: Swapan Shridhar
             Fix For: 3.0.0


For instance during Mpack Advisor's Recommendation call, in case wrong Mpack Version is passed, the error returned as part of API response is following:

{code:title=POST http://[AmbariServer]:8080/api/v1/mpacks/recommendations}
Error parsing services.json file content: null
{code}

One possible reason is if wrong/non-existing Mpack version is passed-in in the REQUEST body.

{code}
{
	"hosts": [
		"host1.openstacklocal",
		"host2.openstacklocal"
	],
	"recommend": "configurations",
	"recommendations": {
		"blueprint": {
                              "mpack_instances": [{
				"name": "HDPCORE",
				"type": "HDPCORE",
				"version": "1.0.0-b121",   ---- > if WRONG_VERSION_NUMBER
                                 .........
{code}


*Fix:* Return information on passed-in Mpack Name and Version, and suggested checking for the Name, version and its existence.

Error retuned after fix:

{code}
Error parsing created services object for Mpack Advisor Python Code. Attempt to read services information for passed-in Mpack : "HDPCORE" and version : "1.0.0-b4121" is NULL. Check passed-in Mpack Name, Version and corresponding stack's existence in cluster.
{code}
