Description

Upgrade HDP 2.6 to HDP 3.0 in Ambari 2.7; EU is supported only (i.e. no RU).

At upgrade time, when the services are starting we should use the new stack version's service_package_folder instead of the old one. This was ok, until the change in FileCache.get_service_base_dir to get the base directory from 'serviceLevelParams' instead of 'commandParams'.

 ...
 "serviceLevelParams": {
 "credentialStoreEnabled": false, 
 "status_commands_timeout": 300, 
 "version": "2.7.3", 
 "service_package_folder": "common-services/YARN/2.1.0.2.0/package"
 },
 ...
 "commandParams": {
 "service_package_folder": "stacks/HDP/3.0/services/YARN/package", 
 "hooks_folder": "stack-hooks", 
 "clusterName": "cluster1", 
 "custom_command": "RESTART", 
 "upgrade_direction": "upgrade", 
 "upgrade_type": "nonrolling_upgrade", 
 "script": "scripts/historyserver.py", 
 "version": "3.0.0.2-155", 
 "forceRefreshConfigTagsBeforeExecution": "true", 
 "request_id": "17", 
 "command_timeout": "900", 
 "script_type": "PYTHON"
 },

The service_package_folder is different; the one in commandParams is the correct value.
