> In Balancer Dispatch.java:
> {code}
>    private void dispatch() {
>       LOG.info("Start moving " + this);
>       Socket sock = new Socket();
>       DataOutputStream out = null;
>       DataInputStream in = null;
>       try {
>         sock.connect(
>             NetUtils.createSocketAddr(target.getDatanodeInfo().getXferAddr()),
>             HdfsConstants.READ_TIMEOUT);
> {code}
> getXferAddr() is called without taking into consideration of dfs.client.use.datanode.hostname
setting, this would possibly fail balancer run issued from outside a cluster.
> Thanks [~caseyjbrotherton] for reporting the issue.
