In Cassandra, the authentication and authorization must be configured on the cassandra.yaml file and two additional files.

Perform the following steps:

1. In the access.properites file we add the access rights to users and the permissions to read and write certain key spaces and columnfamily. Syntax:

           Example 2: 
           hr.cars <ro> = restrada, raparicio 
   

   • In example 1, we give full rights in the Key Space hr to restrada while in example 2 we...
