> In `streams.py` the class `StreamsTestBaseService` lists many log files that are only used in certain tests. For all tests, that do not use those log files, during the test run WARN messages are produced:
> {noformat}
> [WARNING - 2018-05-09 13:51:22,065 - test - compress_service_logs - lineno:131]: Error compressing log /mnt/streams/streams.stdout.0-6: service <StreamsSmokeTestJobRunnerService-0-140502617565072: num_nodes: 1, nodes: ['worker7']>: ubuntu@worker7: Command 'cd "$(dirname /mnt/streams/streams.stdout.0-6)" && f="$(basename /mnt/streams/streams.stdout.0-6)" && tar czf "$f.tgz" "$f" && rm -rf /mnt/streams/streams.stdout.0-6' returned non-zero exit status 2. Remote error message: tar: streams.stdout.0-6: Cannot stat: No such file or directory
> tar: Exiting with failure status due to previous errors
> {noformat}
> Those message spam the output and might be miss leading. We should update the Streams system tests accordingly such that each test only specifies the log-file names it actually uses to avoid the WARN message.
