配置安装Hadoop2.2.0 部署spark 1.0的流程
一、环境描写叙述
本实验在一台Windows7-64下安装Vmware。在Vmware里安装两虚拟机分别例如以下
主机名spark1(192.168.232.147),RHEL6.2-64 操作系统,usernameRoot
从机名spark2(192.168.232.152)。RHEL6.2-64 操作系统,usernameRoot
二、环境准备
1、防火墙禁用。SSH服务设置为开机启动。并关闭SELINUX
2、改动hosts文件
3、配置SSH无password登录
4、准备安装软件包
5、JDK1.7安装及配置
以上操作比較简单。在此就无需赘述。
三. Hadoop2.2集群安装配置
1、创建安装文件夹(在spark2上同做)
mkdir -p /root/install/hadoop
mkdir -p /root/install/hadoop/hdfs
mkdir -p /root/install/hadoop/tmp
mkdir -p /root/install/hadoop/mapred
mkdir -p /root/install/hadoop/hdfs/name
mkdir -p /root/install/hadoop/hdfs/data
mkdir -p /root/install/hadoop/mapred/local
mkdir -p /root/install/hadoop/mapred/system
2、把文件hadoop-2.2.0.x86_64.tar.gz上传到/root/install文件夹下,并解压
3、配置Hadoop环境变量
export HADOOP_HOME=/root/install/hadoop-2.2.0
export HADOOP_CONF_DIR=$HADOOP_HOME/etc/hadoop
export YARN_CONF_DIR=$HADOOP_HOME/etc/hadoop
export PATH=$HADOOP_HOME/bin:$HADOOP_HOME/sbin:$PATH
4、配置Hadoop
(1)向配置hadoop-env.sh文件加入
export JAVA_HOME=/root/install/jdk1.7.0_21
(2)向配置yarn-env.sh文件加入
export JAVA_HOME=/root/install/jdk1.7.0_21
(3)配置core-site.xml
<configuration>
<property>
<name>fs.defaultFS</name>
<value>hdfs://spark1:9000</value>
</property>
<property>
<name>hadoop.tmp.dir</name>
<value>/root/install/hadoop/tmp</value>
</property>
</configuration>
(3)配置hdfs-site.xml
<configuration>
<property>
<name>dfs.name.dir</name>
<value>/root/install/hadoop/hdfs/name</value>
</property>
<property>
<name>dfs.data.dir</name>
<value>/root/install/hadoop/hdfs/data</value>
</property>
<property>
<name>dfs.replication</name>
<value>3</value>
</property>
</configuration>
(4)配置mapred-site.xml
<configuration>
<property>
<name>mapreduce.cluster.local.dir</name>
<value>/root/install/hadoop/mapred/local</value>
</property>
<property>
<name>mapreduce.cluster.system.dir</name>
<value>/root/install/hadoop/mapred/system</value>
</property>
<property>
<name>mapreduce.framework.name</name>
<value>yarn</value>
</property>
<property>
<name>mapreduce.jobhistory.address</name>
<value>spark1:10020</value>
</property>
<property>
<name>mapreduce.jobhistory.webapp.address</name>
<value>spark1:19888</value>
</property> <property>
<name>mapred.child.java.opts</name>
<value>-Djava.awt.headless=true</value>
</property>
<!-- add headless to default -Xmx1024m -->
<property>
<name>yarn.app.mapreduce.am.command-opts</name>
<value>-Djava.awt.headless=true -Xmx1024m</value>
</property>
<property>
<name>yarn.app.mapreduce.am.admin-command-opts</name>
<value>-Djava.awt.headless=true</value>
</property>
</configuration>
(5)配置masters
把localhost改动为spark1
(6)配置slaves
把localhost改动为spark1,spark2,这两个分别各一行
(7)配置好之后将整个安装文件夹复制到spark2的/root/install文件夹下
(8)编写一个脚本,方便改动配置文件时好同步到其它机器
[root@spark1 install]# cat dispatchcfg.sh
#!/bin/bash
for target in spark2
do
scp -r $HADOOP_CONF_DIR $target:/root/install/hadoop-2.2.0/etc
done
(9)格式化Hadoop的Namenode:hadoop namenode -format
5.Hadoop集群启动
(1)start-all.sh
(2)查看相关进程(jps)
6 Hadoop測试
(1)创建一个文件夹/input。并把数据文件上传到文件夹下
hadoop fs -mkdir /input
hadoop fs -put /etc/group /input
(2)执行wordcount
hadoop jar hadoop-mapreduce-examples-2.2.0.jar wordcount /input /output
四、安装部署spark1.0
(1)解压spark-1.0.0-bin-2.2.0.tgz
(2)在文件conf/spark-env.sh加入
export JAVA_HOME=/root/install/jdk1.7.0_21
export SPARK_MASTER_IP=spark1
export SPARK_MASTER_PORT=7077
export SPARK_WORKER_CORES=1
export SPARK_WORKER_INSTANCES=1
export SPARK_WORKER_MEMORY=1g
(3)启动spark集群:sbin/start-all.sh,并查看相关进程
(4)查看执行效果
(5)执行 bin/spark-shell --executor-memory 1g --driver-memory 1g --master spark://spark1:7077
