[jira] [Created] (IMPALA-8790) IllegalStateException: Illegal
reference to non-materialized slot
Quanlong Huang created IMPALA-8790:
--------------------------------------
Summary: IllegalStateException: Illegal reference to non-materialized slot
Key: IMPALA-8790
URL: https://issues.apache.org/jira/browse/IMPALA-8790
Project: IMPALA
Issue Type: Bug
Components: Frontend
Reporter: Quanlong Huang
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;
