[jira] [Commented] (DRILL-7091) Query with EXISTS and correlated
subquery fails with NPE in
HashJoinMemoryCalculatorImpl$BuildSidePartitioningImpl
[ https://issues.apache.org/jira/browse/DRILL-7091?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16790186#comment-16790186 ]
Boaz Ben-Zvi commented on DRILL-7091:
-------------------------------------
The problem may be unrelated to the Hash-Join. Looks like the Hash-Join merely detects a missing part of the schema of the incoming batch from the Project operator.
The plan has a Project under the right side of the Hash-Join:
{noformat}
Project(T5¦¦**=[$0], $f1=[ITEM($0, 'n_regionkey')]) : rowType = RecordType(DYNAMIC_STAR T5¦¦**, ANY $f1)
{noformat}
Then the Hash-Join tries to match "$f1" with the incoming schema, which +has only the first part+: "T5||**" .
Forced the Project push into the scan (by commenting out the "return;" on line 110 in *DrillPushProjectIntoScanRule()* ); this "fixed" the schema of the Project batch to have the two fields.
So somehow Project only gets the first field expression.

> Affects Versions: 1.15.0
> Reporter: Volodymyr Vysotskyi
> Assignee: Boaz Ben-Zvi
> Priority: Major
>
> Steps to reproduce:
> 1. Create view:
> {code:sql}
> create view dfs.tmp.nation_view as select * from cp.`tpch/nation.parquet`;
> {code}
> Run the following query:
> {code:sql}
> SELECT n_nationkey, n_name
> FROM dfs.tmp.nation_view a
> WHERE EXISTS (SELECT 1
> FROM cp.`tpch/region.parquet` b
> WHERE b.r_regionkey = a.n_regionkey)
> {code}
> This query fails with NPE:
> {noformat}
