Cannot connect java client to cassandra with password authentication enabled - authentication

Question

I have a default install of Datastax enterprise on my macbook. I was able to create my keyspace and setup all my applications including using solr.
I am trying to develop a set of steps to turn on password authentication for our dev cluster.
Thus far I have updated /usr/local/dse/resources/cassandra/conf/cassandra.yaml and changed the following properties:
authenticator: PasswordAuthenticator
authorizer: CassandraAuthorizer
I restarted the node and could login and query my keyspace using cqlsh:
cqlsh -u cassandra -p cassandra
At this point I tried setting the Credentials on the Session builder:
Host is: cassandra.host=localhost
Session session = keyspaceToSessionMap.get(keyspace);
if( session == null){
Cluster cluster = Cluster.builder().addContactPoints(hosts)
.withCredentials(username, password)
//.withSSL()
.build();
session = cluster.connect(keyspace);
keyspaceToSessionMap.put(keyspace,session);
}
I could not successfully connect however. So I added a new user and was able to again login via cqlsh but still cannot get the Java driver to connect.
cqlsh -u username -p password
Connected to LocalCluster at 127.0.0.1:9042.
[cqlsh 5.0.1 | Cassandra 2.1.8.689 | DSE 4.7.3 | CQL spec 3.2.0 | Native protocol v3]
I am using 'com.datastax.cassandra:cassandra-driver-dse:2.1.9' via gradle for the driver.
I always get the following stack trace and through debugging can see the username and password are set properly:
Caused by: com.datastax.driver.core.exceptions.AuthenticationException: Authentication error on host localhost/127.0.0.1:9042: Username and/or password are incorrect
at com.datastax.driver.core.Connection$8.apply(Connection.java:376)
at com.datastax.driver.core.Connection$8.apply(Connection.java:346)
This seems like it should be simple but I am stumped.
My dependencies graph in relation to cassandra driver contains the following:
+--- com.datastax.cassandra:cassandra-driver-dse:2.1.9
| \--- com.datastax.cassandra:cassandra-driver-core:2.1.9 -> 2.1.8
| +--- io.netty:netty-handler:4.0.27.Final

| | | \--- io.netty:netty-common:4.0.27.Final
| | +--- io.netty:netty-transport:4.0.27.Final

I created the following test which passes.
Cluster cluster = Cluster.builder().addContactPoints("localhost")
.withCredentials("username", "password")
//.withSSL()
.build();
Session session = cluster.connect("keyspace");
Assert.assertNotNull(session);
The only difference I can tell between the two is that "localhost" is now a constant rather than an array of size 1.

Answer 1

Found I had a trailing whitespace and that was the root cause.
Cluster cluster = Cluster.builder().addContactPoints(hosts)
.withCredentials(username.trim(), password.trim())
//.withSSL()
.build();
