2. Go to spark folder and run below command
./dev/make-distribution.sh --name custom-spark --tgz -Pyarn -Phadoop-2.6 -Dhadoop.version=2.6.0-cdh5.4.8 -Dhbase.version=1.0.0-cdh5.4.8 -Dflume.version=1.5.0-cdh5.4.8 -Dzookeeper.version=3.4.5-cdh5.4.8 -Phive -Phive-thriftserver

tar xvzf spark-2.1.0-bin-custom-spark.tgz
rm -r spark-2.1.0-bin-custom-spark.tgz
