----------------------------
Summary: Windows OS compatibilities
Key: BEAM-1045
URL: https://issues.apache.org/jira/browse/BEAM-1045
Project: Beam
Issue Type: Sub-task
Reporter: Pei He
One known issue is "*" is not allowed in Windows OS.
For example, Paths.get("tempDir/*") might throw when code runs in Windows OS.

This affecting IOChannelFactory.match(String glob).
However, since match only requires support globs in the final component of a
path. (local) FileIOChannelFactory could do things similar as
GcsIOChannelFactory:
First, list all files under the directory path (this won't contain glob, such
as *).
Then, check each returned files whether it matches glob.
In this way, glob (*) stays within Apache Beam's code.
>From match()'s javadoc:
"""
Glob handling is dependent on the implementation. Implementations should
* all support globs in the final component of a path (eg /foo/bar/*.txt),
* however they are not required to support globs in the directory paths.
"""
