There is a special logger config file for inbound console tools. Please, change the logger level from WARN to OFF in [kafka_home]/config/tools-log4j.properties file. The file should look like:

tools-log4j.properties

log4j.rootLogger=OFF, stdout 

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=[%d] %p %m (%c)%n

After it you will get only messages in console.
