I finally have managed to get the HDP Sandbox to run.
I would like to try out the Ambari-Shell. But I am not quite sure, whether it is already included and - if not - how I have to go about installing it.
Can somebody help?
Is there any specific reason that you want to try using "Ambari Shell" ? It's pretty outdated project and there is no recent development happening on that project i guess.
However if you want to use it then you will have to download the JARs seperately or Build the project (ambari-shell) and then start using the JAR via command line (this is because ambari-shell is not available by default with the product).
