Key: IMPALA-5235
URL: https://issues.apache.org/jira/browse/IMPALA-5235

Steps to recreate the issue -
1. With logging level set to 1
./bin/start-impala-cluster.py --log_level=1
[localhost:21000] > select straight_join t1.id, t2.id from functional.alltypes t1 inner join functional.alltypes t2 on t1.id = t2.id limit 5;
Query: select straight_join t1.id, t2.id from functional.alltypes t1 inner join functional.alltypes t2 on t1.id = t2.id limit 5
