------------------------------------
Summary: Improve warning during a Table.execute()
Key: FLINK-19204
URL: https://issues.apache.org/jira/browse/FLINK-19204
Project: Flink
Issue Type: Improvement
Components: Table SQL / API
Reporter: Timo Walther
When running a table program locally that uses `Table.execute().collect` the
logs contain a warning in most of the runs. Logs should not contain a warning
by default, because this is very confusing. At the first glance, it looks like
something went wrong even though the program finished successfully.
