             Summary: Balancer doesn't work with IPFailoverProxyProvider
                 Key: HDFS-10544
                 URL: https://issues.apache.org/jira/browse/HDFS-10544
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Zhe Zhang
            Assignee: Zhe Zhang


Right now {{Balancer}} gets the NN URIs through {{DFSUtil#getNameServiceUris}}, 
which returns logical URIs in HA is enabled. If {{IPFailoverProxyProvider}} is 
used, {{Balancer}} will not be able to start.

I think the bug is at {{DFSUtil#getNameServiceUris}}:
{code}
    for (String nsId : getNameServiceIds(conf)) {
      if (HAUtil.isHAEnabled(conf, nsId)) {
        // Add the logical URI of the nameservice.
        try {
          ret.add(new URI(HdfsConstants.HDFS_URI_SCHEME + "://" + nsId));
{code}

Then {{if}} clause should also consider if the {{FailoverProxyProvider}} has 
{{useLogicalURI}} enabled. If not, {{getNameServiceUris}} should try to resolve 
the physical URI for this nsId.
