Description

https://github.com/apache/hadoop/blob/trunk/hadoop-tools/hadoop-sls/src/main/sample-conf/log4j.properties

 

log4j.appender.test=org.apache.log4j.ConsoleAppender
log4j.appender.test.Target=System.out
log4j.appender.test.layout=org.apache.log4j.PatternLayout
log4j.appender.test.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

log4j.logger=NONE, test

 

This is invalid in current log4j version, if applied this, the test performance will be slow!

 

I think the warn level is enough and required. The level < warn will effect performance
