I am verifying whether gocql can connect to AWS Managed Cassandra Service. I had the same issue to create session.

gocql: unable to create session: control: unable to connect to initial hosts: unexpected authenticator "com.amazon.helenus.auth.HelenusAuthenticator"

I'm all for merging this, anyone can validate it actually works? I don't have access to Amazon's Cassandra service atm. Thanks!

After I modified this change, then try to connect AWS Managed Cassandra Service (MCS), I had another issue in my environment without regard for this issue.

gocql: unable to create session: control: unable to setup connection: Column family TableIdentifier(ksName=system, cfName=local) is not writable

According to my debugging, when gocql create prepared statement and communicate with MCS, then it failed.

row, err := c.query(ctx, "SELECT * FROM system.local WHERE key='local'").rowMap()
info, err = c.prepareStatement(ctx, qry.stmt, qry.trace)

I would appreciate if you could help me.
