-------------------------------------
Summary: system tests: grep logs for errors as part of validation
Key: KAFKA-2861
URL: https://issues.apache.org/jira/browse/KAFKA-2861
Project: Kafka
Issue Type: Bug
Reporter: Geoff Anderson
There may be errors going on under the hood that validation steps do not
detect, but which are logged at the ERROR level by brokers or clients. We are
more likely to catch subtle issues if we pattern match for ERROR as part of
validation, and fail the test in this case.
For example, in https://issues.apache.org/jira/browse/KAFKA-2813, the error is
transient, so our test may pass; however, we still want this issue to be
visible.
To avoid spurious failures, we would probably want to be able to have a
whitelist of acceptable errors.
