Fail to install Ranger KMS in HDP2.5 sandbox

[#1]

Hi, I am trying to install Ranger KMS in HDP 2.5 sandbox using following link.

https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.4.0/bk_Ranger_KMS_Admin_Guide/content/ch02s01.h...

Getting following error message in ambari-agent.log file.

AgentException: 'Script /var/lib/ambari-agent/cache/common-services/RANGER_KMS/0.5.0.2.3/package/scripts/kms_server.py does not exist'

what is the Ambari version are you using? If you have Ambari 2.4.x then can you check

1. "/var/lib/ambari-server/resources/common-services/RANGER_KMS/0.5.0.2.3/package/scripts/kms_server.py" folder/file exist? if that does not exist then your Ambari-server is not installed properly.

2. if that file/folder is present then check for "/var/lib/ambari-agent/cache/common/services/RANGER_KMS/0.5.0.2.3/package/" at the Agent host. basically Ambari-server pushes this files/folders to Ambari-agents. so restart Agent once and then try to check.

Let me know your findings.

I am also facing the same error. I am trying to add Ranger-KMS service from Ambari and while deploying i am seeing the error as "/var/lib/ambari-server/resources/common-services/RANGER_KMS/0.5.0.2.3/package/scripts/kms_server.py" does not exist.

I checked the above mentioned path and script at above path does not exist. I have downloaded HDP 2.5 Sandbox for Virtualbox and both ambari-server and ambari-agent is running on localhost and both are working fine. I think this script should come as part of HDP 2.5. It seems to be a issue in Sandbox image.

Ambari Version 2.4.0.

Could you please suggest the solution?

Thanks

This script/path comes with Ambari-server . if does not exist you can copy that path/files from other setup. these are static files and can be copied to/from every place.
