Sylvain Lebresne resolved CASSANDRA-11002.
------------------------------------------
    Resolution: Not A Problem

I'm sorry but nothing in there indicates a server-side bug. It just appears you either have a network/system configuration problem, or a driver one. I suggest trying the mailing list (probably belong to the java driver one) to get some help but this JIRA is only for tracking bugs and improvements for the server.

> I have created one issue CASSANDRA-10996, but the owner suggest I use datastax java driver to get KeySpaceMetaData, so I downloaded this driver which version is "3.0.0-rc1", I use the following code to connect :
>    Cluster cluster = Cluster.builder()
>         .addContactPoint("192.168.56.11")
>         .build();
>     	KeyspaceMetadata keySpaceMetaData = cluster.getMetadata().getKeyspace(this.keyspace);
> But got the following exception:
> Caused by: com.datastax.driver.core.exceptions.NoHostAvailableException: All host(s) tried for query failed (tried: hwtest1.localdomain/192.168.56.11:9042 (com.datastax.driver.core.exceptions.TransportException: [hwtest1.localdomain/192.168.56.11] Cannot connect))
> 	at com.datastax.driver.core.ControlConnection.reconnectInternal(ControlConnection.java:231)
> 	at com.datastax.driver.core.ControlConnection.connect(ControlConnection.java:77)
> 	at com.datastax.driver.core.Cluster$Manager.init(Cluster.java:1382)
> 	at com.datastax.driver.core.Cluster.getMetadata(Cluster.java:393)
> I also change the cassandra.yaml based on https://github.com/datastax/java-driver/wiki/Connection-requirements
> I also tried use Datastax DevCenter, it can connect to hwtest1.localdomain/192.168.56.11 sussessfully.
