如何禁止ZooKeeper日志输出

程序里使用LOG4j记录日志信息，但是连接到ZooKeeper时会连同ZooKeeper本身的日志信息都输入到的日志里想禁止把ZooKeeper的信息输入到日志里怎么办。已经配置过ZooKeeper的log4j.properties文件，好像不管用。求大神指教
连接ZooKeeper的代码
this.zk = new ZooKeeper(zkAddress,Constants.SESSION_TIME_OUT,this);
在程序代码中是使用如下代码获得日志对象的：
private static final Log LOG = LogFactory.getLog(BSPJobClient.class);


下面是log4j.properties

ZooKeeper的log4j.properties:
# Define some default values that can be overridden by system properties
zookeeper.root.logger=INFO, CONSOLE
zookeeper.console.threshold=ERROR
zookeeper.log.dir=.
zookeeper.log.file=zookeeper.log
zookeeper.log.threshold=INFO
zookeeper.tracelog.dir=.
zookeeper.tracelog.file=zookeeper_trace.log

#
# ZooKeeper Logging Configuration
#

# Format is "<default threshold> (, <appender>)+

# DEFAULT: console appender only
#log4j.rootLogger=${zookeeper.root.logger}
log4j.rootLogger=ERROR,CONSOLE
# Example with rolling log file
#log4j.rootLogger=DEBUG, CONSOLE, ROLLINGFILE

# Example with rolling log file and tracing
#log4j.rootLogger=TRACE, CONSOLE, ROLLINGFILE, TRACEFILE

#
# Log INFO level and above messages to the console
#
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.Threshold=${zookeeper.console.threshold}
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%d{ISO8601} [myid:%X{myid}] - %-5p [%t:%C{1}@%L] - %m%n

#
# Add ROLLINGFILE to rootLogger to get log file output
#    Log DEBUG level and above messages to a log file
log4j.appender.ROLLINGFILE=org.apache.log4j.RollingFileAppender
log4j.appender.ROLLINGFILE.Threshold=${zookeeper.log.threshold}
log4j.appender.ROLLINGFILE.File=${zookeeper.log.dir}/${zookeeper.log.file}

# Max log file size of 10MB
log4j.appender.ROLLINGFILE.MaxFileSize=10MB
# uncomment the next line to limit number of backup files
#log4j.appender.ROLLINGFILE.MaxBackupIndex=10

log4j.appender.ROLLINGFILE.layout=org.apache.log4j.PatternLayout
log4j.appender.ROLLINGFILE.layout.ConversionPattern=%d{ISO8601} [myid:%X{myid}] - %-5p [%t:%C{1}@%L] - %m%n


#
# Add TRACEFILE to rootLogger to get log file output
#    Log DEBUG level and above messages to a log file
log4j.appender.TRACEFILE=org.apache.log4j.FileAppender
log4j.appender.TRACEFILE.Threshold=TRACE
log4j.appender.TRACEFILE.File=${zookeeper.tracelog.dir}/${zookeeper.tracelog.file}

log4j.appender.TRACEFILE.layout=org.apache.log4j.PatternLayout
### Notice we are including log4j's NDC here (%x)
log4j.appender.TRACEFILE.layout.ConversionPattern=%d{ISO8601} [myid:%X{myid}] - %-5p [%t:%C{1}@%L][%x] - %m%n
复制代码

解决办法：
log4j.logger.包名=OFF
