> Key: BEAM-1045
> URL: https://issues.apache.org/jira/browse/BEAM-1045
> Project: Beam
> Issue Type: Sub-task
> Components: io-java-gcp, sdk-java-core
> Reporter: Pei He
> Priority: P3
>
> One known issue is "*" is not allowed in Windows OS.
> For example, Paths.get("tempDir/*") might throw when code runs in Windows OS.
> http://stackoverflow.com/questions/27522581/asterisks-in-java-path
> This affecting IOChannelFactory.resolve(), toPath(), and match().
> For match(), since it 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.
> """
