hadoop yarn hdfs 概念的理解

Fri, 22 Apr 2016 00:13:58 +0800

有几个说的不错的文章，看这里，https://www.ibm.com/developerworks/cn/opensource/os-cn-hadoop-yarn/，来自 ibm，从理论到例子，讲解了 yarn 的产生和变化

http://www.lai18.com/content/1103036.html，对计算框架的历史演变有一个概述

http://www.cnblogs.com/LeftNotEasy/archive/2012/02/18/why-yarn.html，辅助理解 yarn 的一些产生背景

=================

http://www.cnblogs.com/esingchan/p/3917094.html，一一个 wordcount 为例，说明了老 mapreduce 的过程，详细说明了 map sort partition combine shuffle merge reduce 的阶段和概念

hadoop 2.5.2 集群安装

Fri, 18 Mar 2016 16:40:52 +0800

之前写过一个，http://zrj.me/archives/888，不过现在是 2.5.2，东西不同了，安装方式有所变化。

说起来，主要以下几点：

安装 JDK
打通 SSH
停掉防火墙
配置 core-site.xml, maprd-site.xml, hdfs-site.xml，新增了一个 yarn-site.xml

参考这里的文章，http://blog.csdn.net/tang9140/article/details/42869531，http://blog.csdn.net/greensurfer/article/details/39450369，配置文件使用如下：

core-site.xml

<configuration>  
    <property>  
        <name>hadoop.tmp.dir</name>  
        <value>/home/hadoop/tmp</value>  
        <description>Abase for other temporary directories.</description>  
    </property>  
    <property>

mapred-site.xml

        <value>10.0.1.100:19888</value>  
    </property>  
</configuration>

yarn-site.xml

<configuration>  
  
<!-- Site specific YARN configuration properties -->  
    <property>  
        <name>yarn.nodemanager.aux-services</name>  
        <value>mapreduce_shuffle</value>  
    </property>  
    <property>  
        <name>yarn.resourcemanager.address</name>  
        <value>10.0.1.100:8032</value>  
    </property>  
    <property>  
        <name>yarn.resourcemanager.scheduler.address</name>  
        <value>10.0.1.100:8030</value>  
    </property>  
    <property>  
        <name>yarn.resourcemanager.resource-tracker.address</name>  
        <value>10.0.1.100:8031</value>  
    </property>  
    <property>  
        <name>yarn.resourcemanager.admin.address</name>  
        <value>10.0.1.100:8033</value>  
    </property>  
    <property>  
        <name>yarn.resourcemanager.webapp.address</name>  
        <value>10.0.1.100:8088</value>  
    </property>  
</configuration>

最后配置 slaves 文件，没有了 master 文件

然后格式化 namenode，输出如下

zrj@FWSVRLPT01:~/hadoop-2.5.2$ ./bin/hdfs namenode -format
