如何启用hdfs和mapred审计日志？(How to enable hdfs and mapred audit logs?)

 我是windows中的hadoop-2.6.0用户。 我想启用hdfs和mapred日志。 我可以通过在hadoop-env.cmd中设置以下属性来启用hdfs审核日志，但无法为mapred启用审核日志。 
 
set HDFS_AUDIT_LOGGER=INFO,RFAAUDIT
 
 如果我在hadoop-env.cmd中设置了上述变量，那么hdfs-audit.log文件存储在％HADOOP_LOG_DIR％中。 
 
 我想启用mapred审核日志记录。 在％HADOOP_HOME％\ etc \ hadoop中可用的log4j.properties中，我可以看到下面粘贴的mapred的日志属性 
 
 mapred审计日志记录 
 
mapred.audit.logger=INFO,NullAppender
mapred.audit.log.maxfilesize=256MB
mapred.audit.log.maxbackupindex=20
log4j.logger.org.apache.hadoop.mapred.AuditLogger=${mapred.audit.logger}
log4j.additivity.org.apache.hadoop.mapred.AuditLogger=false
log4j.appender.MRAUDIT=org.apache.log4j.RollingFileAppender
log4j.appender.MRAUDIT.File=${hadoop.log.dir}/mapred-audit.log
log4j.appender.MRAUDIT.layout=org.apache.log4j.PatternLayout
log4j.appender.MRAUDIT.layout.ConversionPattern=%d{ISO8601} %p %c{2}: %m%n
log4j.appender.MRAUDIT.MaxFileSize=${mapred.audit.log.maxfilesize}
log4j.appender.MRAUDIT.MaxBackupIndex=${mapred.audit.log.maxbackupindex}
 
 但无法启用mapred审核日志记录。 当我更改以下属性时，存储在％HADOOP_LOG_DIR％中的空文件mapred-audit.log 。 
 
mapred.audit.logger=INFO,MRAUDIT

log4j.additivity.org.apache.hadoop.mapred.AuditLogger=true

 如何启用mapred审核日志？ 
 
 非常感谢帮助。 

I am hadoop-2.6.0 user in windows. I want to enable hdfs and mapred logs. I could enable hdfs audit log by setting the following property in hadoop-env.cmd but cannot enabled audit log for mapred.
 
set HDFS_AUDIT_LOGGER=INFO,RFAAUDIT
 
If i set the above variable in hadoop-env.cmd then hdfs-audit.log file stored in the %HADOOP_LOG_DIR%.
 
I want to enable mapred audit logging. In log4j.properties available in the %HADOOP_HOME%\etc\hadoop, i could see the logging properties for mapred which is pasted below
 
mapred audit logging
 
mapred.audit.logger=INFO,NullAppender
mapred.audit.log.maxfilesize=256MB
mapred.audit.log.maxbackupindex=20
log4j.logger.org.apache.hadoop.mapred.AuditLogger=${mapred.audit.logger}
log4j.additivity.org.apache.hadoop.mapred.AuditLogger=false
log4j.appender.MRAUDIT=org.apache.log4j.RollingFileAppender
log4j.appender.MRAUDIT.File=${hadoop.log.dir}/mapred-audit.log
log4j.appender.MRAUDIT.layout=org.apache.log4j.PatternLayout
log4j.appender.MRAUDIT.layout.ConversionPattern=%d{ISO8601} %p %c{2}: %m%n
log4j.appender.MRAUDIT.MaxFileSize=${mapred.audit.log.maxfilesize}
log4j.appender.MRAUDIT.MaxBackupIndex=${mapred.audit.log.maxbackupindex}
 
But cannot enable mapred audit logging. When i change the following properties then an empty file mapred-audit.log stored in the %HADOOP_LOG_DIR%.
 
mapred.audit.logger=INFO,MRAUDIT

log4j.additivity.org.apache.hadoop.mapred.AuditLogger=true
