> While testing fixes for the parquet nullable support I ran into an issue with
> unexpected results. I was selecting several columns out of file parquet file,
> which supports project pushdown. Currently the planner still includes a
> project operation after the scan in this case (to properly modify schema in
> the case of array indexing, project pushdown into scans is currently not
> supposed to be changing structure). I pulled the physical plan from the query
> and ran it without the extra project (as I was not selecting any array
> values) and got the expected results.
> Here is the query I ran, the file is too large to attach so you can e-mail me
> to get a copy of it.
> select pig_schema,ss_sold_date_sk,ss_item_sk,ss_cdemo_sk,ss_addr_sk,
> ss_hdemo_sk from store_sales
