[jira] [Updated] (BEAM-9123) HadoopResourceId returns wrong directory name

     [ https://issues.apache.org/jira/browse/BEAM-9123?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Marek Simunek updated BEAM-9123:
--------------------------------
    Description: 
 _HadoopResourceId_ returns for directory uri wrong fileName() which doesnt conform _ResourceId_ interface javadoc

{color:#629755}Returns the name of the file or directory..{color}

String {color:#ffc66d}getFilename{color}(){color:#cc7832}; {color}

 
{code:java}
URI hdfsClusterBaseUri = new URI(configuration.get("fs.defaultFS") + "/");
HadoopResourceId hadoopResourceId =
new HadoopResourceId(hdfsClusterBaseUri.resolve("/dirA/file1"));{code}
Expected behavior: 

_hadoopResourceId.getCurrentDirectory().getFilename()_ returns *dirA*

Actual behavior:
 _hadoopResourceId.getCurrentDirectory().getFilename()_ returns *""*

The problem is that uri for folder is ending with '*/*' and  [getFilesystem|#L68]] is using hadoop Path.getName() which returns everything after last slash.

is using hadoop Path.getName() which returns everything after last slash.
