not able to connect to cassandra cluster: "no authenticator found in Cluster configuration"

[Sebastian Vagedes]

Hi,

I'm currently giving the new beta a shot. It runs smoothly as long as I don't enable authentication and authorization in my C* cluster. I can't tell if this problem is "new" because I'm just starting here.

Here's my setup:

• single C* instance, "authenticator: PasswordAuthenticator" and "authorizer: CassandraAuthorizer" set in cassandra.yaml
• user/password created following this tutorial @ apache.org
• single K* instance with "kairosdb.datastore.cassandra.auth.user=x" and "kairosdb.datastore.cassandra.auth.password=y"

And here's the exception I get when I try to start K*:

com.google.inject.ProvisionException: Guice provision errors:

1) Error injecting constructor, com.datastax.driver.core.exceptions.AuthenticationException: Authentication error on host [...]/[...]:9042: Host [...]/[...]:9042 requires authentication, but no authenticator found in Cluster configuration

Can anybody think of a solution here? User/Pass are correct, I double-checked of course. There are no trailing whitespaces @kairosdb.properties or anything like that...

Hi,

   I had the same problem with C* 3.11，did you solve it?

Hi Cheng Gf,

yes, it's no big deal:

The property for the user is not labeled correctly. Brian merged my pull request about a month ago to the develop branch.

Here's the difference:

-#kairosdb.datastore.cassandra.auth.username=admin +#kairosdb.datastore.cassandra.auth.user_name=admin

I'm connecting successfully to C* now.
