Jason Altekruse commented on DRILL-1701:
----------------------------------------
The initial patch posted did not address the real issue with the file being
read. The file was a completely flat schema, however when I checked the file
with the parquet-tools I mis interpreted the output because the file actually
contained json structures within a var-binary field, which I mistook as output
to represent a map in the file. The real issue was a bug reading nullable
dictionary encoded data, which is posted with the 'b' version of the patch.
> Drill chooses the optimized reader that only supports flat data, rather than
> the one that supports complex in the case where there is a simple
> non-repeated map type
