For the context, @tillrohrmann asked in this comment[1] about the excessive INFO level logging in AZP. It appears that INFO level logging from org.apache.flink.streaming.connectors.kafka are printed in AZP due to the following reasons: - By searching for "log4j.configurationFile" in [2], we could see that `tools/ci/log4j.properties` is used to configure the log4j level in AZP. - `org.apache.flink.streaming.connectors.kafka` is specifically updated to use ConsoleAppender instead of FileAppender inside the file `tools/ci/log4j.properties` I guess the questions are: - Is it expected that AZP test uses `tools/ci/log4j.properties` instead of `src/test/log4j2-test.properties` for log4j configuration? - Why do we specifically set `org.apache.flink.streaming.connectors.kafka` to use `ConsoleAppender` in `tools/ci/log4j.properties`? @rmetzger, @zentol: do you have any suggestion? Thanks.
