一、下载须知
软件准备：
spark-1.0.0-bin-hadoop1.tgz 下载地址：spark1.0.0
scala-2.10.4.tgz 下载下载：Scala 2.10.4
hadoop-1.2.1-bin.tar.gz 下载地址：hadoop-1.2.1-bin.tar.gz
jdk-7u60-linux-i586.tar.gz 下载地址：去官网下载就行，这个1.7.x都行
二、安装步骤
hadoop-1.2.1安装步骤，请看： http://my.oschina.net/dataRunner/blog/292584
1.解压：
tar -zxvf scala-2.10.4.tgz mv scala-2.10.4 scala tar -zxvf spark-1.0.0-bin-hadoop1.tgz mv spark-1.0.0-bin-hadoop1 spark
2. 配置环境变量：
vim /etc/profile (在最后一行加入以下内容就行)
export HADOOP_HOME_WARN_SUPPRESS=1
export JAVA_HOME=/home/big_data/jdk
export JRE_HOME=${JAVA_HOME}/jre
export CLASS_PATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export HADOOP_HOME=/home/big_data/hadoop
export HIVE_HOME=/home/big_data/hive
export SCALA_HOME=/home/big_data/scala
export SPARK_HOME=/home/big_data/spark
export PATH=.:$SPARK_HOME/bin:$SCALA_HOME/bin:$HIVE_HOME/bin:$HADOOP_HOME/bin:$JAVA_HOME/bin:$PATH3.修改spark的spark-env.sh文件
cd spark/conf cp spark-env.sh.template spark-env.sh vim spark-env.sh (在最后一行加入以下内容就行) export JAVA_HOME=/home/big_data/jdk export SCALA_HOME=/home/big_data/scala export SPARK_MASTER_IP=192.168.80.100 export SPARK_WORKER_MEMORY=200m export HADOOP_CONF_DIR=/home/big_data/hadoop/conf
然后就配置完毕勒！！！（就这么简单，艹，很多人都知道，但是共享的人太少勒）
三、测试步骤
hadoop-1.2.1测试步骤，请看： http://my.oschina.net/dataRunner/blog/292584
1.验证scala
[root@master ~]# scala -version Scala code runner version 2.10.4 -- Copyright 2002-2013, LAMP/EPFL [root@master ~]# [root@master big_data]# scala Welcome to Scala version 2.10.4 (Java HotSpot(TM) Client VM, Java 1.7.0_60). Type in expressions to have them evaluated. Type :help for more information. scala> 1+1 res0: Int = 2 scala> :q
2.验证spark (先启动hadoop-dfs.sh)
[root@master big_data]# cd spark
[root@master spark]# cd sbin/start-all.sh
（ 也可以分别启动
[root@master spark]$ sbin/start-master.sh
可以通过 http://master:8080/ 看到对应界面
[root@master spark]$ sbin/start-slaves.sh park://master:7077
可以通过 http://master:8081/ 看到对应界面
）
[root@master spark]# jps
[root@master ~]# jps

5007 Master (spark的)
6150 Jps
4832 SecondaryNameNode （hadoop的）
5107 Worker （spark的）
4734 DataNode （hadoop的）
可以通过 http://192.168.80.100:8080/ 看到对应界面
[root@master big_data]# spark-shell
