Answer 1

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, console
log4j.rootLogger = DEBUG, console
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.target=System.out
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=%d{yy/MM/dd HH:mm:ss} %p %c{2}: %m%n

it happens because of the hadoop logging framework
