-

i trying suppress message

using spark's default log4j profile: org/apache/spark/log4j-defaults.properties

when run spark app. i've redirected info messages successfully, message keeps on showing up. ideas appreciated.

even simpler cd spark_home/conf mv log4j.properties.template log4j.properties open log4j.properties , change info error. here spark_home root directory of spark installation.

some may using hdfs spark storage backend , find logging messages generated hdfs. alter this, go hadoop_home/etc/hadoop/log4j.properties file. change hadoop.root.logger=info,console hadoop.root.logger=error,console. once again hadoop_home root of hadoop installation me /usr/local/hadoop.
