hadoop2.2伪分布安装加2.2源码编译

配置linux基本环境:

     --> java、ip、hostname、hosts、iptables、chkconfig、ssh环境配置

hadoop2.2安装在linux64位机器上,需要对源码进行编译:

    首先安装google的protobuf

    yum install glibc-header

    yum install gcc

    yum install gcc-c++

    yum install make

    yum install cmake

    yum install openssl-devel

    yum install ncurses-devel

    tar zxvf protobuf-2.5.0.tar.gz

    cd protobuf-2.5.0 && ./configure && make check && make install 

    然后安装maven-3.0.5,配置 环境变量

    下载hadoop2.20-src,解压后,执行mvn package -DskipTests -Pdist native 编译。

修改hadoop配置文件,etc/hadoop 目录下的配置文件core-site.xml,hdfs-site.xml,yarn-site.xml,mapred-site.xml

    文件core-site.xml

<configuration>
        <property>
                <name>fs.defaultFS</name>
                <value>hdfs://hadoop0:9000</value>
        </property>
        <property>
                <name>hadoop.tmp.dir</name>
                <value>/usr/local/hadoop-2.2.0/tmp</value>
        </property>
        <property>
                 <name>fs.trash.interval</name>
                 <value>1440</value>
        </property>
</configuration>

    文件hdfs-site.xml

<configuration>
    <property>
        <name>dfs.replication</name>
        <value>1</value>
    </property>
    <property>
        <name>dfs.permissions</name>
        <value>false</value>
    </property>
</configuration>

    文件yarn-site.xml

<configuration>
        <property>
                <name>yarn.nodemanager.aux-services</name>
                <value>mapreduce_shuffle</value>
        </property>
</configuration>

    文件mapred-site.xml

<configuration>
    <property>
        <name>mapreduce.framework.name</name>
        <value>yarn</value>
    </property>
</configuration>

启动

    启动——格式化:

    bin/hdfs namenode -format

    

    启动——hdfs

    sbin/hadoop-daemon.sh start namenode 对应端口:50070
    sbin/hadoop-daemon.sh start datanode

    启动——yarn
    sbin/yarn-daemon.sh start resourcemanager 对应端口:8088
    sbin/yarn-daemon.sh start nodemanager

    启动——historyserver

    sbin/mr-jobhistory-daemon.sh start historyserver

    测试上传:bin/hadoop fs -put LICENSE.txt /license

    hadoop1默认block大小是64兆,hadoop2默认大小是128兆

测试单词计数:

    bin/hadoop jar share/hadoop/mapreduce/hadoop-mapreduce-examples-2.2.0.jar wordcount /license /out
    启动jobhistory 查看作业运行日志 sbin/mr-jobhistory-daemon.sh start historyserver
    hadoop应用在nodemanager上跑的。
    MapReduce的ApplicationMaster叫MRAppMaster
    nodemanager是有多个,resourcemanager只有一个
