[SOLVED] Disable INFO logs in aws kcl

I'm running on Ubuntu 16.04 & Java 8. kcl generate thousands of INFO log lines. Does any one know how to enable only ERROR and WARN logs?

*I have also the same question for kpl.

I don't have a logfile.

<configuration>
    .........

    <logger name="com.amazonaws.services.kinesis.producer" level="warn"/>
    <logger name="com.amazonaws.services.kinesis.clientlibrary" level="warn"/>

    .........
</configuration>

Log levels: https://www.slf4j.org/api/org/apache/commons/logging/Log.html. You can also define a prefix of packages.
