---------------------------------
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}
