---------------------------------
Summary: OOM with Hive native scan enabled on TPCH-100 parquet,
query 05.q
Key: DRILL-3900
URL: https://issues.apache.org/jira/browse/DRILL-3900
Project: Apache Drill
Issue Type: Bug
Components: Functions - Hive
Affects Versions: 1.2.0
Reporter: Chun Chang
TPCH-100 parquet dataset. Configure Hive 1.0 pointing to the parquet files as
external tables. Enable Hive native scan.
{noformat}
alter system set `store.hive.optimize_scan_with_native_readers`=true;
{noformat}
Run TPCH query 05 through Hive, drillbit runs out of memory. Same query goes
through dfs completes successfully. (Disable hive native scan, drill also runs
out of memory through hive.)
We expect with hive native scan turned on, query should finish.
