1、下 载 scala2.11.4版本 下载地址为：http://www.scala-lang.org/download/2.11.4.html
2、解压和安装：
3、编辑 ~/.bash_profil文e 件 增加 SCALA_HOME
export JAVA_HOME=/home/spark/opt/java/jdk1.6.0_37
export
CLASSPATH=.:$JAVA_HOME/jre/lib:$JAVA_HOME/lib:$JAVA_HOME/lib/tools.j
ar
export SCALA_HOME=/home/spark/opt/scala-2.11.4
export HADOOP_HOME=/home/spark/opt/hadoop-2.6.0
PATH=$PATH:$HOME/bin:$JAVA_HOME/bin:${SCALA_HOME}/bin
立即生效 source ~/.bash_profile
http://d3kbcqa49mib13.cloudfront.net/spark-1.2.0-bin-hadoop2.4.tgz
7、在 master主机配置 spark ：
export JAVA_HOME=/home/spark/opt/java/jdk1.6.0_37
export
CLASSPATH=.:$JAVA_HOME/jre/lib:$JAVA_HOME/lib:$JAVA_HOME/lib/tools.jar
export SCALA_HOME=/home/spark/opt/scala-2.11.4
export HADOOP_HOME=/home/spark/opt/hadoop-2.6.0
export SPARK_HOME=/home/spark/opt/spark-1.2.0-bin-hadoop2.4
PATH=$PATH:$HOME/bin:$JAVA_HOME/bin:${SCALA_HOME}/bin:${SPARK_HO
ME}/bin:${HADOOP_HOME}/bin
