1.安装JDK

2.安装scala 2.9.3

Spark 0.7.2 依赖 Scala 2.9.3, 我们必须要安装Scala 2.9.3.

下载 scala-2.9.3.tgz 并 保存到home目录(已经在sg206上）.

$ tar -zxf scala-2.9.3.tgz

$ sudo mv scala-2.9.3 /usr/lib

$ sudo vim /etc/profile

# add the following lines at the end

export SCALA_HOME=/usr/lib/scala-2.9.3

export PATH=$PATH:$SCALA_HOME/bin

# save and exit vim

#make the bash profile take effect immediately

source /etc/profile

# test

$ scala -version

3.building spark

cd /home

tar -zxf spark-0.7.3-sources.gz

cd spark-0.7.3

sbt/sbt package (需要git环境 yum install git）

4.配置文件

spark-env.sh

############

export SCALA_HOME=/usr/lib/scala-2.9.3

export SPARK_MASTER_IP=172.16.48.202

export SPARK_WORKER_MEMORY=10G

#############

slaves

将从节点IP添加至slaves配置文件

5.启动和停止

bin/start-master.sh - Starts a master instance on the machine the script is executed on.

bin/start-slaves.sh - Starts a slave instance on each machine specified in the conf/slaves file.

bin/start-all.sh - Starts both a master and a number of slaves as described above.

bin/stop-master.sh - Stops the master that was started via the bin/start-master.sh script.

bin/stop-slaves.sh - Stops the slave instances that were started via bin/start-slaves.sh.

bin/stop-all.sh - Stops both the master and the slaves as described above.

6. 浏览master的web UI(默认http://localhost:8080). 这是你应该可以看到所有的word节点，以及他们的CPU个数和内存等信息。
