Jason Altekruse commented on DRILL-1871:
----------------------------------------
Sorry I forgot to run the unit tests before uploading, I made a bad assumption
that I would receive some kind of place-holder decompressor in the case where a
matching one could not be found. Apparently it actually returns null so I have
to handle creating a normal stream as were before if no compression is
associated with the extension.
> JSON reader cannot read compressed files
