Jun Rao commented on KAFKA-1354:
--------------------------------
The issue is related to slf4j. slf4j only provides the api. The user is
expected to provide the actual binding implementation. You can include either
slf4j-simple.jar or slf4j-log4j12.jar in the classpath. Then the warning will
go away.
