Not sure if you are talking about kafka-console-consumer commands, if yes this is what I did:

[training@confluent-training-vm ~]$ cd /etc/kafka
[training@confluent-training-vm kafka]$ grep DEBUG *.properties
log4j.properties:# Change to DEBUG or TRACE to enable request logging
log4j.properties:# Access denials are logged at INFO level, change to DEBUG to also 
log allowed accesses
tools-log4j.properties:log4j.rootLogger=DEBUG, stderr

So, you just need to edit /etc/kafka/tools-log4j.properties file and remove DEBUG (or replace it for exmaple by INFO and WARM log levels on above line

tools-log4j.properties:log4j.rootLogger=INFO, WARM, stderr
