[jira] [Created] (IMPALA-7116) Prevent tests from fetching too many results.

Lars Volker created IMPALA-7116:
-----------------------------------

             Summary: Prevent tests from fetching too many results.
                 Key: IMPALA-7116
                 URL: https://issues.apache.org/jira/browse/IMPALA-7116
             Project: IMPALA
          Issue Type: Improvement
          Components: Infrastructure
    Affects Versions: Impala 2.13.0, Impala 3.1.0
            Reporter: Lars Volker


In IMPALA-7008 a rogue test tried to fetch 100M rows, which caused the Python test runner itself to be OOM killed. We should find a maximum number of rows that we will fetch in tests and then fail tests if a query returns more rows. We might have to fix some tests as we go.
