Hadoop log4j not working as No appenders could be found for logger (org.apache.hadoop.metrics2.lib.MutableMetricsFactory)
1- Create the file log4j.properties and put it in the location of
src/main/resources
the content of the log4j.properties
hadoop.root.logger=DEBUG, consolelog4j.rootLogger = DEBUG, consolelog4j.appender.console=org.apache.log4j.ConsoleAppenderlog4j.appender.console.target=System.outlog4j.appender.console.layout=org.apache.log4j.PatternLayoutlog4j.appender.console.layout.ConversionPattern=%d{yy/MM/dd HH:mm:ss} %p %c{2}: %m%nit happens because of the hadoop logging framework
Create a log4j.properties file with something like the following:
hadoop.root.logger=DEBUG, consolelog4j.rootLogger = DEBUG, consolelog4j.appender.console=org.apache.log4j.ConsoleAppenderlog4j.appender.console.target=System.outlog4j.appender.console.layout=org.apache.log4j.PatternLayoutlog4j.appender.console.layout.ConversionPattern=%d{yy/MM/dd HH:mm:ss} %p %c{2}: %m%n
