Cassandra: how to setup client-to-node encryption?

I've set up Cassandra client-to-node encryption using DataStax guide

Client_encription_options from cassandra.yaml file:

 client_encryption_options:
    enabled: true
    keystore: /opt/key/.keystore
    keystore_password: cassandra
    cipher_suites:[TLS_RSA_WITH_AES_128_CBC_SHA,TLS_DHE_RSA_WITH_AES_128_CBC_SHA,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA]

The client using the default Java System properties for SSL:

-Djavax.net.ssl.trustStore=/opt/app/conf/.truststore -Djavax.net.ssl.trustStorePassword=cassandra

But after connecting got error in Cassandra log:

INFO [Native-Transport-Requests:12] 2015-02-11 11:45:52,456 Message.java (line 397) Unexpected exception during request; channel = [id: 0xfb3df0e3, /192.168.43.13:32885 => /192.168.43.10:9042]

I'm using Cassandra 2.0.10.71, Java 1.7.0_75 with Java Cryptography Extension libs

This is an INFO messages that suggest that a no ssl package has been set to your Cassandra node. It seems that there is something trying to connect to your Cassandra node.

Have a look to the source code of the Netty java file which raise the exception. org.jboss.netty.handler.ssl.SslHandler.decode(SslHandler.java:871)

  if (nonSslRecord) {
       // Not an SSL/TLS packet
        NotSslRecordException e = new NotSslRecordException(
        "not an SSL/TLS record: " + ByteBufUtil.hexDump(in));
        in.skipBytes(in.readableBytes());
            ctx.fireExceptionCaught(e);
            setHandshakeFailure(ctx, e);
   }
