> Impala test suite harness fails to reset some options in SQL sessions

> Key: IMPALA-5986
> URL: https://issues.apache.org/jira/browse/IMPALA-5986
> Project: IMPALA
> Issue Type: Bug
> Components: Infrastructure
> Affects Versions: Impala 2.9.0, Impala 2.10.0, Impala 2.11.0
> Reporter: Tim Wood
> Assignee: Tim Wood
> Fix For: Impala 2.11.0

>
> This bug arose while characterizing TPC-DS tests that flap.
> Runs of the full TPC-DS suite display results for various tests that
> variously fail or succeed in absence of code or environment changes. All
> failures are connected with displays of the scale of decimal values. Some
> tests contain SET DECIMAL_V2=1; statements. I theorized that this option was
> getting left on in SQL connections and exposed to subsequent tests.
> The main test suite driver file,
> $IMPALA_HOME/tests/common/impala_test_suite.py, contains logic to reset
> options in the SQL session between tests, however its regex to detect these
> statements fails for statements that contain digits (SET_PATTERN =
> re.compile(...)).
