1、安装scala：
在SparkNode01~03节点安装：
cd /opt
tar xzvf scala-2.11.12.tgz
mv scala-2.11.12 scala
scp -r scala @SparkNode03:/opt
vi /etc/profile
SCALA_HOME=/opt/scala
PATH=$PATH:$SCALA_HOME/bin
source /etc/profile
scala -version
2、安装Spark
在SparkNode01~03节点安装：
cd /opt
tar xzvf spark-2.2.1-bin-hadoop2.7.tgz
mv spark-2.2.1-bin-hadoop2.7 spark
cd spark/conf
cp spark-env.sh.template spark-env.sh
vi spark-env.sh
添加：
export JAVA_HOME=/usr/local/java/jdk1.8.0_121
export SCALA_HOME=/opt/scala
export HADOOP_HOME=/opt/hadoop
export HADOOP_CONF_DIR=/opt/hadoop/tc/hadoop
export SPARK_MASTER_PORT=7077
export SPARK_EXECUTOR_CORES=2
export SPARK_EXECUTOR_MEMORY=1024m
export SPARK_EXECUTOR_INSTANCES=1
cp slaves.template slaves
vi slaves
添加：
SparkNode01
SparkNode02
SparkNode03
在hdfs上传spark的jar包，并修改/opt/spark/conf/spark-defaults.conf
cd /opt/hadoop/bin
./hadoop fs -mkdir /spark_jars
./hadoop fs -put /opt/spark/jars/* /spark_jars
cp spark-defaults.conf.template spark-defaults.conf
vi spark-defaults.conf
添加：
spark.yarn.jars=hdfs://Master01:9000/spark_jars/*
验证：
./spark-submit --class org.apache.spark.examples.SparkPi --master yarn --deploy-mode cluster --driver-memory 1g --executor-memory 1g --executor-cores 1 --num-executors 3 /opt/spark/examples/jars/spark-examples_2.11-2.2.1.jar 10
