Hi there,

I have used this manual: http://www.datastax.com/documentation/cassandra/2.0/webhelp/index.html#cassandra/security/security_config_native_authenticate_t.html to use the PasswordAuthenticator but now everytime I run a nodetool repair it repairs the system_auth keyspace which needs about 10 to 15 minutes.

nodetool repair
[2013-10-31 09:39:59,623] Nothing to repair for keyspace 'system'
[2013-10-31 09:39:59,811] Starting repair command #1, repairing 1280 ranges for keyspace system_auth

This is what I get on every node every time i start a repair.

Is this expected behaviour? I have only added a new superuser and changed the password of the default superuser so there should not be too much to do at all.

Thanks for your help!
Dennis
