Keyspace system_auth does not exist?

Question

I wanted to execute the following command:

alter KEYSPACE system_auth 
WITH replication =  
       { 'class' : 'SimpleStrategy', 
         'replication_factor' : 2 };

Is it normal that system_auth does not appear as a keyspace?

Basically the following error occurs:

Bad Request: Unknown keyspace system_auth

Also, how do I even browse existing keyspaces? Is it possible to view them even in cqlsh?

Answer 1

This key database is not created when used authenticator: AllowAllAuthenticator (by default). So configure authenticator, reboot node and you will be fine

Answer 2

system_auth cassandra. , cassandra.yaml, "authenticator: PasswordAuthenticator" "authorizer: CassandraAuthorizer".

cql "desc keyspaces" "select * from system.schema_keyspaces;".
