Embed Apache ZooKeeper in Jetty generates Debug log message

I am using Jetty 8 and ZooKeeper 3.4.5. When I connect to ZooKeeper, jetty keep generating DEBUG level message. How to suppress it?

16:54:56.757 [main-SendThread(127.0.0.1:2181)] DEBUG o.a.z.client.ZooKeeperSaslClient - Could not retrieve login configuration: java.lang.SecurityException: Unable to locate a login configuration

I added log4j.properties under src folder:

# Set root logger level to DEBUG and its only appender to A1.
log4j.rootLogger=DEBUG, A1

# A1 is set to be a ConsoleAppender.
log4j.appender.A1=org.apache.log4j.ConsoleAppender

# A1 uses PatternLayout.
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%-4r - [%t] %-5p %c %x - %m%n

log4j.logger.org.apache.zookeeper.ZooKeeper=INFO

Still no luck.

I have checked again my included library, and I found out that LogBack was included. I think JVM load logback instead of log4j. Once I supply logback.xml, the problem is solved.

Something like this in config should help:

<logger name="com.apache.zookeeper" level="info">
   <!-- appenders -->
</logger>
