-------------------------------------
Summary: Filesystems.matchSingleFileSpec throws away the actual
failure exception
Key: BEAM-8173
URL: https://issues.apache.org/jira/browse/BEAM-8173
Project: Beam
Issue Type: Bug
Components: sdk-java-core
Reporter: Kenneth Knowles
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.
