Hi,

 

            I changed the default log level of hadoop from INFO to ERROR by
setting the property hadoop.root.logger to error in
<hadoop>/conf/log4j.properties

 

            But when I start namenode, the INFO logs are seen in the log
file. I did a workaround and found that  HADOOP_ROOT_LOGGER is hard coded to
INFO in 

            hadoop-daemon.sh and hadoop script files in <hadoop>/bin. Is
there anything to do with that or they are provided for any purpose??

 

            PS: I am using hadoop 0.20.1

 

 Thanks,

  Gokul
