historically, there issue support local file system in apache beam didn't support pattern matching on windows os. didn't apply in other case -- local file system on other operating systems, google cloud storage on operating system, etc. worked expected.

there plenty of improvements in area recently, , there more in progress. believe specific exception fixed, i'd encourage try again newer version.
