java.io.EOFException while retrieving data from Riak

Question

I am trying to execute a simple fetching of data as a string from Riak.

We are trying to execute a sample code and we are getting the error. It's a Java code written for fetching data from Riak

I made sure riak is running by Sudo Riak Start

Error as follows:

Exception in thread "main" com.basho.riak.client.RiakRetryFailedException: java.io.EOFException

    public static void main(String[] args) throws RiakException
    {
        //IRiakClient riakClient = RiakFactory.httpClient();
        IRiakClient client = RiakFactory.pbcClient("127.0.0.1", 8098);
        Bucket myBucket = client.fetchBucket("TestBucket").execute();
        IRiakObject myObject = myBucket.fetch("TestKey").execute();
        // note that getValueAsString() will return null here if there's no value in Riak
        System.out.println(myObject.getValueAsString());

        client.shutdown();
    }
}

Thank you so much for all your help.

I have found the problem!

My port # was 8087 instead of 8098

We need to configure that in /etc/riak/app.conf (Under API settings)

I have reconfigured that and It fixed it.

Thank you!
