Spark环境的安装方法

本篇内容主要讲解"Spark环境的安装方法"，感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷，实用性强。下面就让小编来带大家学习"Spark环境的安装方法"吧!

1、准备工作

○ 下载工具

scala-2.9.3：一种编程语言，下载地址：http://www.scala-lang.org/files/archive/scala-2.9.3.tgz
spark-1.4.0：必须是编译好的Spark，如果下载的是Source，则需要自己根据环境使用SBT或者MAVEN重新编译才能使用，编译好的Spark下载地址：http://mirror.bit.edu.cn/apache/spark/spark-1.4.0/spark-1.4.0-bin-hadoop2.4.tgz

○ 搭建hadoop环境，此处不再详细描述如何搭建，请自行百度。

2、安装scala-2.9.3

解压scala-2.9.3.tgz#tar -zxvf scala-2.9.3.tgz配置SCALA_HOME#vi /etc/profile添加如下环境export SCALA_HOME=/home/apps/scala-2.9.3export PATH=.:$SCALA_HOME/bin:$PATH测试scala安装是否成功直接输入 scala

3、安装spark-1.4.0

解压spark-1.4.0.tgz#tar -zxvf spark-1.4.0.tgz配置SPARK_HOME#vi /etc/profile添加如下环境export SCALA_HOME=/home/apps/spark-1.4.0export PATH=.:$SPARK_HOME/bin:$SPARK_HOME/sbin:$PATH

4、修改Spark配置文件

复制slaves.template和 spark-env.sh.template各一份#cp  spark-env.sh.template  spark-env.sh#cp  slaves.template slavesslaves，此文件是指定子节点的主机,直接添加子节点主机名即可在spark-env.sh末端添加如下几行：#JDK安装路径export JAVA_HOME=/root/app/jdk#SCALA安装路径export SCALA_HOME=/root/app/scala-2.9.3#主节点的IP地址export SPARK_MASTER_IP=192.168.1.200#分配的内存大小export SPARK_WORKER_MEMORY=200m#指定hadoop的配置文件目录export HADOOP_CONF_DIR=/root/app/hadoop/etc/hadoop#指定worker工作时分配cpu数量export SPARK_WORKER_CORES=1#指定spark实例，一般1个足以export SPARK_WORKER_INSTANCES=1#jvm操作，在spark1.0之后增加了spark-defaults.conf默认配置文件，该配置参数在默认配置在该文件中export SPARK_JAVA_OPTS#spark-defaults.conf中还有如下配置参数SPARK.MASTER    //spark://hostname:8080SPARK.LOCAL.DIR    //spark工作目录（做shuffle的目录）SPARK.EXECUTOR.MEMORY //spark1.0抛弃SPARK_MEM参数,使用该参数

5、测试spark安装是否成功

在主节点机器上启动顺序1、先启动hdfs(./sbin/start-dfs.sh)2、启动spark-master(./sbin/start-master.sh)3、启动spark-worker(./sbin/start-slaves.sh)4、jps查看进程有    主节点：namenode、secondrynamnode、master    从节点：datanode、worker5、启动spark-shell15/06/21 21:23:47 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable15/06/21 21:23:47 INFO spark.SecurityManager: Changing view acls to: root15/06/21 21:23:47 INFO spark.SecurityManager: Changing modify acls to: root15/06/21 21:23:47 INFO spark.SecurityManager: SecurityManager: authentication disabled;
