问题
I have a 3 node cassandra cluster and via my unit test in Java, I first create a keyspace and then create a column family within that keyspace. Sometimes the unit tests passes but randomly I keep getting the following error. I am using the latest datastax 2.1.4 java driver and the cassandra version in 2.1.0.

And in the system.log file of cassandra I see the following exception:

Also, I verified via devcenter, the keyspace didn't get created.
回答1:
Without seeing your code, my guess is you need a sleep in between creating the keyspace and trying to create tables in it. You probably need to give the keyspace definition a couple seconds to propagate to all the nodes in your cluster before you try to use it.
回答2:
It would help as noted to see your configuration class. We are using ClassPathCQLDataSet to issue our statements and create keyspace at same go (link to ClassPathCqlDataSet documentation, note that boolean on position 2 and 3 tell it to create and delete keyspace). db.cql is file where we hold create table statments. Here is our configuration which might help you:

cluster = Cluster.builder().addContactPoints(contact_points).withPort(port).build();
session = cluster.connect();
LOGGER.info("Initialize keyspace");
final CQLDataLoader cqlDataLoader = new CQLDataLoader(session);
cqlDataLoader.load(new ClassPathCQLDataSet(CQL, false, true, keyspace));
}

cluster = null;
}
}
}
