If a user wants to develop an application to access the HBase service, he first applies for a machine-to-machine account teste1, and sets the permission to access the HBase service: then download the keytab file of the account and use the account to run the application. Subsequent business requirements for this application require access to the Hive service. After the tested user is granted access to the Hive component, the user's keytab file needs to be re-downloaded.
