Subject [jira] [Commented] (HADOOP-11618) DelegateToFileSystem always uses default FS's default port
Date Sat, 07 Mar 2015 07:47:38 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-11618?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14351472#comment-14351472

Gera Shegalov commented on HADOOP-11618:

Thanks for updating the patch, [~brahmareddy]. The latest patch still does not quite test
what was broken, and what I was suggesting in the previous comment. Although the test names
002 include defaultURI, they actually don't call {{FileSystem.setDefaultUri}}. 

It's a also not necessary to cast to (FtpFs). 

Both tests also should use the same ftp URI without port in both tests.
Assuming we move fs.AbstractFileSystem.ftp.impl to core-default.xml (I now think it makes
more sense), that is what I am looking for in the test class.
public class TestDelegateToFileSystem {

  private static final String FTP_DUMMYHOST = "ftp://dummyhost";
  private static final URI FTP_URI_NO_PORT = URI.create(FTP_DUMMYHOST);
  private static final URI FTP_URI_WITH_PORT =

  private void testDefaultUriInternal(String defaultUri)
      throws UnsupportedFileSystemException {
    final Configuration conf = new Configuration();
    FileSystem.setDefaultUri(conf, defaultUri);
    final AbstractFileSystem ftpFs = AbstractFileSystem.get(FTP_URI_NO_PORT,
    Assert.assertEquals(FTP_URI_WITH_PORT, ftpFs.getUri());

  public void testDefaultURIwithOutPort() throws Exception {

  public void testDefaultURIwithPort() throws Exception {

{{testDefaultURIwithPort}} without your fix breaks as explained:
java.lang.AssertionError: expected:<ftp://dummyhost:21> but was:<ftp://dummyhost:8020>
