Aman Sinha created DRILL-1406:
---------------------------------

             Summary: Regression: In the web UI the query profile shows Parquet Group Scan
incorrectly reporting 0 rows
                 Key: DRILL-1406
                 URL: https://issues.apache.org/jira/browse/DRILL-1406
             Project: Apache Drill
          Issue Type: Bug
          Components: Metadata
    Affects Versions: 0.5.0
            Reporter: Aman Sinha


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}
