-----------------------------------

             Summary: HadoopResourceId returns wrong directory name
                 Key: BEAM-9123
                 URL: https://issues.apache.org/jira/browse/BEAM-9123
             Project: Beam
          Issue Type: Bug
          Components: io-java-hadoop-file-system
    Affects Versions: 2.17.0
            Reporter: Marek Simunek


 _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|[https://github.com/apache/beam/blob/master/sdks/java/io/hadoop-file-system/src/main/java/org/apache/beam/sdk/io/hdfs/HadoopResourceId.java#L68]]
is using hadoop Path.getName() which returns everything after last slash.
