> Key: IMPALA-8790
> URL: https://issues.apache.org/jira/browse/IMPALA-8790
> Project: IMPALA
> Issue Type: Bug
> Components: Frontend
> Reporter: Quanlong Huang
> Assignee: Quanlong Huang
> Priority: Major
> Attachments: foo.parq
>

> Reproduce:
> {code:sql}
> $ hdfs dfs -put foo.parq hdfs:///tmp
> impala> create table foo (uid string, cid string) stored as parquet;
> impala> load data inpath 'hdfs:///tmp/foo.parq' into table foo;
> {code}
> With the stats, the following query hits an IllegalStateException:
> {code:sql}
> impala> compute stats foo;
> impala> explain select uid, cid,
> rank() over (partition by uid order by count(*) desc)
> from (select uid, cid from foo) w
> group by uid, cid;
> ERROR: IllegalStateException: Illegal reference to non-materialized slot: tid=1 sid=2{code}
> Without the stats, it runs successfully:
> {code:sql}
> impala> drop stats foo;
> impala> explain select uid, cid,
> rank() over (partition by uid order by count(*) desc)
> from (select uid, cid from foo) w
> group by uid, cid;
