Summary: Tuple caching correctness verification fails for
query_test.test_queries.TestQueriesTextTables.test_random
Key: IMPALA-13893
URL: https://issues.apache.org/jira/browse/IMPALA-13893
Project: IMPALA
Issue Type: Bug
Components: Backend
Affects Versions: Impala 5.0.0
Reporter: Joe McDonnell
When running with tuple cache correctness verification,
query_test.test_queries.TestQueriesTextTables.test_random fails with the
following error:

What's happening is that two tuple caching locations have the same cache key
because they are scanning the same table. Tuple caching correctness
verification fails because one location has already removed locations when the
other wants to do correctness verification. One way to fix this is to
incorporate the plan node id into the filenames.
