1. Log in your ambari-server with user root, or with a sudoer (requires to add sudo before every command).

2. Copy/Download the Jethro management pack (mpack) to your ambari-server (jethro-mpack.tar.gz - don't ungz it).

3. Install the Jethro management pack on your ambari-server:

   Code Block
   ambari-server install-mpack --mpack=<path to the mpack file>

4. Restart the ambari-server:

   Code Block
   ambari-server restart

5. Create an Extension Link, to link the installed extension to Amabri according to your HDP stack version:

   Code Block
   curl -u admin:admin -H 'X-Requested-By: ambari' -X POST -d '{"ExtensionLink": {"stack_name": "HDP", "stack_version":"<your stack version>", "extension_name": "JethroExt", "extension_version": "1.0.0"}}' http://localhost:8080/api/v1/links/

   For example, if you are running HDP 2.6.0:

   Code Block
   curl -u admin:admin -H 'X-Requested-By: ambari' -X POST -d '{"ExtensionLink": {"stack_name": "HDP", "stack_version":"2.6", "extension_name": "JethroExt", "extension_version": "1.0.0"}}' http://localhost:8080/api/v1/links/

    *To find the HDP stack version - Open Ambari, click on the Admin tab and then select the Versions tab.
