-------------------------------------
Summary: dcheck in impala::AggregationNode::Close
Key: IMPALA-7397
URL: https://issues.apache.org/jira/browse/IMPALA-7397
Project: IMPALA
Issue Type: Bug
Components: Backed
Affects Versions: Impala 3.1.0
Reporter: Michael Brown
Assignee: Thomas Tauber-Marshall
The dcheck is {{Check failed: expr_results_pool() == nullptr ||
expr_results_pool()->total_allocated_bytes() == 0}}. The random query generator
found this numerous times. I was able to reproduce it, and the dcheck fails on
all 3 impalads. Stack is the same on all 3.

An example pared down query:
{noformat}
SELECT
c_custkey,
MIN(c_nationkey)
FROM tpch_kudu.customer
GROUP BY
c_custkey,
c_nationkey
HAVING
(EXTRACT(HOUR FROM CAST('0' AS TIMESTAMP) + INTERVAL c_nationkey YEAR)) !=
c_custkey;
{noformat}
I could not figure out a more simplified HAVING expression that triggers the
bug.
