Hi Srmitta,

In my lab I cannot see any warn or info while doing hadoop commands. Please try the below setting in the hdfs-log4j :

 

hadoop.root.logger=INFO,WARN,console
hadoop.log.dir=.
hadoop.log.file=hadoop.log

Hi Arun

 

Seeing this Information warnings on client side, created log4j.properties file on client and added properties what you suggested and passed log4j.properties file using -Dlog4j.configuration to client application, this didn't help, still seeing messages.

 

Only way I could stop that message is by setting .level = SEVERE in IBM JDK logging.properties file. Wondering if there is another way I could stop this message without making changes to logging.properties file.

 

Thanks

Srinivasa
