-----------------------------------
Summary: test_shutdown_executor fails with timeout waiting for
query target state
Key: IMPALA-7931
URL: https://issues.apache.org/jira/browse/IMPALA-7931
Project: IMPALA
Issue Type: Bug
Components: Infrastructure
Affects Versions: Impala 3.2.0
Reporter: Lars Volker
On a recent S3 test run test_shutdown_executor hit a timeout waiting for a
query to reach state FINISHED. Instead the query stays at state 5 (EXCEPTION).

The query was {{select count(*) from functional_parquet.alltypes where sleep(1)
= bool_col}}.
It seems that the query took longer than expected and was still running when
the executor shut down.
