Description

 HadoopResourceId returns for directory uri wrong fileName() which doesnt conform ResourceId interface javadoc

Returns the name of the file or directory..

String getFilename();

 

URI hdfsClusterBaseUri = new URI(configuration.get("fs.defaultFS") + "/");
HadoopResourceId hadoopResourceId =
new HadoopResourceId(hdfsClusterBaseUri.resolve("/dirA/file1"));

Expected behavior: 

hadoopResourceId.getCurrentDirectory().getFilename() returns dirA

Actual behavior:
hadoopResourceId.getCurrentDirectory().getFilename() returns ""

The problem is that uri for folder is ending with '/' and  getFileName() is using hadoop Path.getName() which returns everything after last slash.
