Work Description: piotr-szuberski commented on pull request #11137:
[BEAM-8173] Fix shadowing the actual failure exception in Filesystems…
URL: https://github.com/apache/beam/pull/11137
….matchSingleFileSpec
The code before masked the actual failure exception.
The MatchResult usecase assumes that if there was an error then calling for
metadata throws an exception with the information of the actual error. I
changed the code to propagate the exception when accessing the metadata throws.

> At [1] the result of a non-OK match causes an exception to be thrown. But the
> exception does not include the actual cause of the failure, so it cannot be
> efficiently debugged. It appears that the design of MatchResult is that it
> should call metadata() without bothering to check status, so that the
> underlying exception can be re-raised and caught and put in the chain of
> causes, as it should be.
