Jinfeng Ni resolved DRILL-3667.
-------------------------------
Resolution: Fixed
I think the root cause of this JIRA is same as DRILL-3690, which has merged the
fix to master.
If you see the error again, please re-open the JIRA.
> Random Assertion Error while planning
> -------------------------------------
>
> Key: DRILL-3667
> URL: https://issues.apache.org/jira/browse/DRILL-3667
> Project: Apache Drill
> Issue Type: Bug
> Components: Query Planning & Optimization
> Affects Versions: 1.2.0
> Reporter: Rahul Challapalli
> Assignee: Mehant Baid
> Priority: Critical
> Fix For: 1.2.0
>
> Attachments: error.log, hive.ddl, lineitem_hierarchical_intint.tar
>
>
> git.commit.id.abbrev=b55e232
> When assertions are enabled, the below query produces an Assertion Error
> randomly.
> {code}
> explain plan for select l_orderkey, l_partkey, l_quantity, l_shipdate,
> l_shipinstruct, `year`, `month` from
> hive.lineitem_text_partitioned_hive_hier_intint where (`year` IN
> (negative(-1993)) and `month`=sqrt(100)) or (`year` IN (cast(abs(-1994.0) as
> int)) and `month`=cast('5' as int));
> {code}
> When Assertions are disabled, we randomly get a wrong plan where we prune
> away things which we should not have pruned resulting in wrong results. Again
> this is random.
