Jozef Vilcek updated BEAM-5180:
-------------------------------
Description:
Recently this commit
https://github.com/apache/beam/commit/3fff58c21f94415f3397e185377e36d3df662384
introduced more strict schema parsing which is breaking the contract between
_FileResultCoder_ and _FileSystems.matchNewResource()_.
Coder takes _ResourceId_ and serialize it via `_toString_` methods and then
relies on filesystem being able to parse it back again. Having strict
_scheme://_ breaks this at least for Hadoop filesystem which use _URI_ for
_ResourceId_ and produce _toString()_ in form of `_hdfs:/some/path_`
I guess the _ResourceIdCoder_ is suffering the same problem.
Either scheme parsing should be less strict or ResourceId.toString() for hadoop
fixed
