Hadoop框架搭建（二）-配置YARN

1.在/opt/programs/hadoop-2.6.0/etc/hadoop/下

 

cp mapred-site.xml.template mapred-site.xml
vi mapred-site.xml
在编辑状态下，添加
<configuration>
    <property>
        <name>mapreduce.framewrok.name</name>
        <value>yarn</value>
    </property>
</configuration>

2.在/opt/programs/hadoop-2.6.0/etc/hadoop/下

vi yarn-site.xml
在编辑状态下添加
<configuration>
    <property>
        <name>yarn.nodemanager.aux-services</name>
        <value>mapreduce_shuffle</value>
    </property>
    <property>
        <name>yarn.resourcemanager.hostname</name>
        <value>hadoop1</value>
    </property>
    <property>
        <name>yarn.nodemanager.resource.memory-mb</name>
        <value>1024</value>
    </property>
    <property>
        <name>yarn.nodemanager.resource.cpu-vcores</name>
        <value>1</value>
    </property>
</configuration>

3.在/opt/programs/hadoop-2.6.0/etc/hadoop/下

vi slaves
删掉localhost添加hadoop1

4.在/opt/programs/hadoop-2.6.0/下启动

sbin/yarn-daemon.sh start resourcemanager
sbin/yarn-daemon.sh start nodemanager

5.web界面

访问hadoop1:8088
