> HDFS Balancer does not respect dfs.client.use.datanode.hostname
> ---------------------------------------------------------------
>
> Key: HDFS-9100
> URL: https://issues.apache.org/jira/browse/HDFS-9100
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: balancer & mover, HDFS
> Reporter: Yongjun Zhang
> Assignee: Casey Brotherton
>
> 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.
