Error running client code

[Benjamin Parrish]

I am having what seems to be a usual error people see, but I am not sure 
administratively what to do to fix it.

This is my code:

public static void main(String[] args) throws TableNotFoundException, 
AccumuloException, AccumuloSecurityException {
        String instanceName = "accumulo";
        String zooServers = "10.200.20.37";
        Instance inst = new ZooKeeperInstance(instanceName, zooServers);

        Connector conn = inst.getConnector("root", "secret");
                
        Text rowID = new Text("row1");
        Text colFam = new Text("myColFam");
        Text colQual = new Text("myColQual");
        ColumnVisibility colVis = new ColumnVisibility("public");
        long timestamp = System.currentTimeMillis();

        Value value = new Value("myValue".getBytes());

        Mutation mutation = new Mutation(rowID);
        mutation.put(colFam, colQual, colVis, timestamp, value);
                
        long memBuf = 1000000L; // bytes to store before sending a batch
        long timeout = 1000L; // milliseconds to wait before sending
        int numThreads = 10;

        BatchWriter writer = conn.createBatchWriter("table", memBuf, timeout, 
numThreads);

        writer.addMutation(mutation);

        writer.close();
}

This is the error I see in Eclipse:

13/09/13 12:10:22 WARN impl.ServerClient: Failed to find an available server in 
the list of servers: [127.0.0.1:9997:9997 (120000)]

Everything is operational to the best of my knowledge.  I can run scans on 
tables in the terminal.
