> This seems like a regression.... the web UI  shows the Parquet Group Scan reporting 0
rows processed even though it clearly has processed several rows.   The downstream operators
do report valid number of rows.  
> Here's an example query and a partial profile output: 
> {code:sql}
> select o_custkey from (select o_custkey from orders group by o_custkey) where o_custkey
< 10 order by o_custkey;
> Fragment #0 - Operator 5 (HASH_AGGREGATE)
> Fragment	Setup	Process	Wait	Max Batches	Max Records
> #0 - 0	0.083	0.648	0.000	46	1500000
> Fragment #0 - Operator 6 (PARQUET_ROW_GROUP_SCAN)
> Fragment	Setup	Process	Wait	Max Batches	Max Records
> #0 - 0	0.000	0.026	0.000	0	0
> {code}
