Lars Volker created IMPALA-8603:
-----------------------------------
Summary: Some custom cluster tests print error messages after
IMPALA-1653 was fixed
Key: IMPALA-8603
URL: https://issues.apache.org/jira/browse/IMPALA-8603
Project: IMPALA
Issue Type: Bug
Components: Infrastructure
Affects Versions: Impala 3.3.0
Reporter: Lars Volker
Assignee: Thomas Tauber-Marshall
The fix for IMPALA-1653 seems to introduce error messages at the end of some
custom cluster tests. It looks like tests are affected that leave the cluster
down.

HiveServer2Error: Failed after retrying 3 times
{noformat}
The tests still return 0 (success) but I found this confusing.
[~twmarshall] - I'm not sure what the best workaround here is. Should we ignore
"Could not connect to" in {{impala_connection.py}}.
