Cassandra：启动Cassandra之前如何设置密码？

Question

Enabling password authentication by editing cassandra.yaml works fine for me. I can use bin/cqlsh -u cassandra -p cassandra to login.

I have the following in cassandra.yaml:

authenticator: PasswordAuthenticator

What I would like to do is to set the password for user "cassandra" BEFORE I start Cassandra. For obvious security reasons, I do not want to start Cassandra with the default password. Can this be done? How?

I am a total Cassandra newbie using Cassandra 2.0.2.

No. Don't expose Cassandra to the network before changing the password. (Note that Cassandra defaults to only listening on localhost.)
