Subject [jira] Created: (HDFS-1304) There is no unit test for HftpFileSystem.open(..)

There is no unit test for HftpFileSystem.open(..)
-------------------------------------------------

                 Key: HDFS-1304
                 URL: https://issues.apache.org/jira/browse/HDFS-1304
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: test
            Reporter: Tsz Wo (Nicholas), SZE


HftpFileSystem.open(..) first opens an URL connection to namenode's FileDataServlet and then
is redirected to datanode's StreamFile servlet.  Such redirection does not work in the unit
test environment because the redirect URL uses real hostname instead of localhost.

One way to get around it is to use fault-injection in order to replace the real hostname with
localhost.
