    [ https://issues.apache.org/jira/browse/HADOOP-5259?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12673416#action_12673416 ] 

Koji Noguchi commented on HADOOP-5259:
--------------------------------------

Looking at FileSystem.java:checkapth()
{noformat} 
      if (thatAuthority == null &&                // path's authority is null
          thisAuthority != null) {                // fs has an authority
        URI defaultUri = getDefaultUri(getConf()); // & is the default fs
        if (thisScheme.equalsIgnoreCase(defaultUri.getScheme()) &&
            thisAuthority.equalsIgnoreCase(defaultUri.getAuthority()))
          return;
      }
{noformat} 

With output of hdfs:/user/knoguchi/outputpath

that Authority is null
this Authority is aaa.bbb.ccc
this Scheme is hdfs
default Scheme is hdfs
default Authority is aaa.bbb.ccc:8020

FileSystem.getDefaultUri simply takes "fs.default.name" and don't know about NameNode.DEFAULT_PORT.
