Error while connecting to Cassandra using Java Driver for Apache Cassandra 1.0 from com.example.cassandra

Question

While connecting to Cassandra client using java driver for Cannsandra by DataStax, it is throwing following error..

Exception in thread \"main\" com.datastax

Answer 1

I had this issue and it was sorted by setting the ReadTimeout in SocketOptions:

Cluster cluster = Cluster.builder().addContactPoint("localhost").build();
cluster.getConfiguration().getSocketOptions().setReadTimeoutMillis(HIGHER_TIMEOUT);

Answer 2

In my case this was a port issue, which I forgot to update

Old RPC port is 9160
New binary port is 9042

Answer 3

I too encountered this problem, and it was caused by a simple error in the statement that was being submitted.

session.prepare(null);

Obviously, the error message is misleading.

Answer 4

Check below points:

i) check server ip

ii) check listening port

iii) data-stack client dependency must match the server version.

About the yaml file, latest versions has below properties enabled:

    start_native_transport: true
    native_transport_port: 9042

Answer 5

Assuming you have default configurations in place, check the driver version compatibility. Not all driver versions are compatible with all versions of Cassandra, though they claim backward compatibility. Please see the below link.

http://docs.datastax.com/en/developer/java-driver/3.1/manual/native_protocol/

I ran into a similar issue & changing the driver version solved my problem.

Note: Hopefully, you are using Maven (or something similar) to resolve dependencies. Otherwise, you may have to download a lot of dependencies for higher versions of the driver.

Answer 6

Edit

/etc/cassandra/cassandra.yaml 

and change

rpc_address to 0.0.0.0,broadcast_rpc_address and listen_address to ip address of the cluster.
