DOAN DuyHai created CASSANDRA-6489:
--------------------------------------

             Summary: ClassCastException when using EACH_QUORUM with SimpleStrategy
                 Key: CASSANDRA-6489
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-6489
             Project: Cassandra
          Issue Type: Bug
          Components: Core
         Environment: Cassandra 2.0.3
Java Driver Core 2.0.0-rc2
            Reporter: DOAN DuyHai
            Priority: Minor


When sending requests with EACH_QUORUM consistency and SimpleStrategy, the Java driver reports
the following exception:


<pre>
ERROR [11:38:36,075][] org.apache.cassandra.transport.messages.ErrorMessage@:fromException
Unexpected exception during request

 There should be proper error message instead of a ClassCastException. This is a minor issue
though.
