> 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.
