--------------------------------------
Summary: Crash in RawValue::PrintValue() when running
query_test/test_chars.py
Key: IMPALA-13506
URL: https://issues.apache.org/jira/browse/IMPALA-13506
Project: IMPALA
Issue Type: Sub-task
Components: Frontend
Affects Versions: Impala 4.5.0
Reporter: Joe McDonnell
I ran into a crash with the Calcite planner when running test_chars.py. Here
are reproducing conditions:
{noformat}
# Start Impala cluster with --use_calcite_planner=true
# Connect to Impala using Beeswax
bin/impala-shell.sh --protocol=beeswax
# Run these statements
use functional;
WITH numbered AS (
SELECT *, row_number() over (order by cs) as rn
FROM chars_tiny)
SELECT *
FROM (
SELECT CASE WHEN rn % 2 = 0 THEN cs END cs,
CASE WHEN rn % 2 = 1 THEN cl END cl,
CASE WHEN rn % 3 = 0 THEN vc END vc
FROM numbered
UNION ALL
SELECT CASE WHEN rn % 2 = 1 THEN cs END cs,
CASE WHEN rn % 2 = 0 THEN cl END cl,
CASE WHEN rn % 3 = 1 THEN vc END vc
FROM numbered) v{noformat}
It hits this DCHECK with this stacktrace:
