Riak＆Java - com.fasterxml.jackson.core.JsonParseException：意外的字符（'<'（代码60））

Question

I'm trying to execute this code (I deployed Riak on a Master/Slave cluster). I'm using Riak's JAVA API:

import com.basho.riak.client.IRiakClient;
import com.basho.riak.client.IRiakObject;
import com.basho.riak.client.RiakException;
import com.basho.riak.client.RiakFactory;
import com.basho.riak.client.bucket.Bucket;

public class RiakTest {


public static void main(String[] args) throws RiakException
{

    String myData = "This is my data";
    IRiakClient riakClient = RiakFactory.httpClient("http://riak.master.ip.adress:8098");

    Bucket myBucket = riakClient.fetchBucket("TestBucket").execute();
    myBucket.store("TestKey", myData).execute();
    riakClient.shutdown();

}


}

And I have this error raised:

Exception in thread "main" com.basho.riak.client.RiakRetryFailedException: com.fasterxml.jackson.core.JsonParseException: Unexpected character ('<' (code 60)): expected a valid value (number, String, array, object, 'true', 'false' or 'null')

Do you have any idea where the problem could come from ?

Thanks

Answer 1

Because that's not a valid Riak URL.

It should be http://riak.master.ip.adress:8098/riak
