Chun Chang created DRILL-3900: --------------------------------- 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
