Daniel Becker commented on IMPALA-12137:
----------------------------------------
[~rizaon] I don't think it will help because this is about the case when the
data is not compressed. I created this Jira on behalf of [~csringhofer] because
Jira didn't work for him, he'll fill it with more info.
> Parquet scanner should not copy uncompressed data in dict encoded pages
