How to stop messages from being displayed on spark console

Question

I'm receiving various log msgs on spark shell and I want to remove them. On a website, I came to know that it can be done by editing the log4j.properties file

Here are the contents of log4j.properties

# Define the root logger with appender file
log4j.rootCategory=WARN, console
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.target=System.err
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=%d{yy/MM/dd HH:mm:ss} %p %c{1}: %m%n

# Settings to quiet third party logs that are too verbose
log4j.logger.org.eclipse.jetty=WARN
log4j.logger.org.eclipse.jetty.util.component.AbstractLifeCycle=ERROR
log4j.logger.org.apache.spark.repl.SparkIMain$exprTyper=INFO
log4j.logger.org.apache.spark.repl.SparkILoop$SparkILoopInterpreter=INFO

In your log4j.properties file you need to replace this line 

log4j.rootCategory=INFO, console

with

log4j.rootCategory=ERROR, console.

Hope it helps
