准备Linux环境【JAVA,IP,hostname,hosts,iptables,chkconfig,ssh】 不会配置的找1.0下面的伪分布环境搭建

下载稳定版2.2.0

修改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> //开启器垃圾箱功能

                 <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>

启动格式化

bin/hdfs namenode  -format

启动hdfs

sbin/hadoop-daemon.sh start namenode

sbin/hadoop-daemon.sh start datanode

启动yarn

sbin/yarn-daemon.sh start resourcemanager

sbin/yarn-daemon.sh start nodemanager

启动historyserver

sbin/mr-jobhistory-daemon.sh start historyserver
