                 URL: https://issues.apache.org/jira/browse/BEAM-2069
             Project: Beam
          Issue Type: Bug

Beam FileSystem currently has a getCurrentDirectory method that returns the current resource id if it's a directory, or the parent directory if it's a directory.

To implement this you need to know whether or not a particular path is a directory or not.

I'm trying to implement the Hadoop FileSystem implementation, and it's not clear if it's possible. Hadoop's Paths do not end a / if they are a directory (they are stripped), nor do hadoop paths tell you if something is a directory, so it's not possible to determine if a given path is a file that does not have a suffix, or a directory.

It's not clear to me that all file systems can determine whether a path is a directory and thus I don't believe it can be implemented reliably.

The only usages of getCurrentDirectory that I could find are in tests so it's not clear we actually need this.

I propose that we remove this method.
