Install Spark, and Configure along with above setting up environment variables. Configure the JAVA_HOME and HADOOP_CONF_DIR in conf/spark-env.sh file:

export HADOOP_CONF_DIR=/home/user/hadoop-2.7.1/etc/hadoop
export JAVA_HOME=/home/user/jdk1.8.0_60

and Define the slave(put dns names of slaves) in spark Conf directory:

conf/slaves

and start the spark on YARN by using command:

bin/spark-shell --master yarn-client

Thats It You done !!!!
