Sungwoo Park commented on HIVE-26654:
-------------------------------------
HIVE-26986 has been added as a subtask because TPD-DS query 71 returns wrong
results on 1TB ORC table. HIVE-26986 also fixes HIVE-26621 and HIVE-26660.
> Test with the TPC-DS benchmark
> -------------------------------
>
> Key: HIVE-26654
> URL: https://issues.apache.org/jira/browse/HIVE-26654
> Project: Hive
> Issue Type: Bug
> Affects Versions: 4.0.0-alpha-2
> Reporter: Sungwoo Park
> Priority: Major
>
> This Jira reports the result of running system tests using the TPC-DS
> benchmark. The test scenario is:
> 1) create a database consisting of external tables from a 100GB or 1TB TPC-DS
> text dataset
> 2) load a database consisting of ORC tables
> 3) compute column statistics
> 4) run TPC-DS queries
> 5) check the results for correctness
> For step 5), we will compare the results against Hive 3 (which has been
> tested against SparkSQL and Presto). We use Hive on Tez.
