How to set the log level of Kafka clients?

[Pradhan V]

Hi,

How can the log level of the Kafka clients (Producers/Consumers) be set?

Is it by using a log4j.properties file? Or, is there a way it can be
programmatically set, as well?

What are the possible options that are presently available to configure the
log level of the clients?

Thanks,
Pradhan.
