------------------------------------
Summary: HadoopFileSystem doesn't Support Recursive Globs (**)
Key: BEAM-6851
URL: https://issues.apache.org/jira/browse/BEAM-6851
Project: Beam
Issue Type: Improvement
Components: io-java-hadoop
Reporter: Kyle Winkelman
The LocalFileSystem supports recursive globs, **, through use of the [glob
syntax|https://docs.oracle.com/javase/tutorial/essential/io/fileOps.html#glob]
and it would be nice to similarly allow it in the HadoopFileSystem.
The FileSystem docs say:
{code:java}
All FileSystem implementations should support glob in the final hierarchical
path component of ResourceIdT. This allows SDK libraries to construct file
system agnostic spec. FileSystems can support additional patterns for
user-provided specs.
{code}
This clearly points out that recursive globs aren't required but may be
supported as an additional pattern for user-provided specs.
