> ORC-570 is an ABI change to the way getFileSystem() by adding an another exception to the implementation.
> To accept and use that change requires waiting for an ORC release, while this patch serves the same purpose though falls back for a retry for FileSystem.get() in case the supplier fails at runtime.
> Also as a side-note, the FS.get() call is always used in the cases where the file is not being read from a cache such as EncodedOrcFile (so the upstream API change might be overkill).
