spark0.9分布式安装

http://blog.csdn.net/myboyliu2007/article/details/18990277

spark安装包：spark-0.9.0-incubating-bin-hadoop2.tgz

操作系统：     CentOS6.4

jdk版本：      jdk1.7.0_21

1. Cluster模式

1.1安装Hadoop

用VMware Workstation创建三台CentOS虚拟机，hostname分别设置为 master,slaver01, slaver02，设置SSH无密码登陆，安装hadoop，然后启动hadoop集群。参考我的这篇博客，hadoop-2.2.0分布式安装.

1.2 Scala

在三台机器上都要安装 Scala 2.9.3,按照我的博客SparK安装的步骤。JDK在安装Hadoop时已经安装了。进入master节点。

$ cd

$ scp -r scala-2.10.3 root@slaver01:~

$ scp -r scala-2.10.3 root@slaver02:~

 

1.3在master上安装并配置Spark

解压

$ tar -zxf spark-0.9.0-incubating-bin-hadoop2.tgz

$ mv spark-0.9.0-incubating-bin-hadoop2 spark-0.9

在 inconf/spark-env.sh中设置SCALA_HOME

$ cd ~/spark-0.9/conf

$ mv spark-env.sh.template spark-env.sh

$ vi spark-env.sh

# add the following line

export SCALA_HOME=/root/scala-2.10.3

export JAVA_HOME=/usr/java/jdk1.7.0_21

export SPARK_MASTER_IP=192.168.159.129

export SPARK_WORKER_MEMORY=1000m

# save and exit

在conf/slaves,添加Sparkworker的hostname,一行一个。

$ vim slaves

slaver01

slaver02

master

# save and exit

（可选）设置 SPARK_HOME环境变量，并将SPARK_HOME/bin加入PATH

$ vim /etc/profile

# add the following lines at the end

export SPARK_HOME=$HOME/spark-0.9

export PATH=$PATH:$SPARK_HOME/bin

# save and exit vim

#make the bash profile take effect immediately

$ source /etc/profile

1.4在所有worker上安装并配置Spark

既然master上的这个文件件已经配置好了，把它拷贝到所有的worker即可。注意，三台机器spark所在目录必须一致，因为master会登陆到worker上执行命令，master认为worker的spark路径与自己一样。

$ cd

$ scp -r spark-0.9 root@slaver01:~

$ scp -r spark-0.9 root@slaver02:~

1.5启动 Spark集群

在master上执行

$ cd ~/spark-0.9

$ ./sbin/start-all.sh

检测进程是否启动

[root@master ~]# jps

3200 SecondaryNameNode

7350 Master

7470 Worker

3025 NameNode

8022 Jps

3332 ResourceManager

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

1.6运行Spark自带的例子

运行SparkPi

$ cd ~/spark-0.9

root@master spark-0.9]# ./bin/run-example org.apache.spark.examples.SparkPi local
