【技术】Hadoop安装——本地安装伪分布模式

(1)特点：在一台机器上模拟一个分布式环境具备hadoop的所有功能。
        HDFS：NameNode+DataNode+SecondarynameNode
        Yarn：ResourceManager+NodeManager
(2)步骤：
** step1:hadoop-env.sh **
JAVA_HOME=/opt/moudle/jdk1.8.0_181

** step2:hdfs-site.xml **
<!-- 配置数据块的冗余度，默认是3 -->
<property>
    <name>dfs.replication</name>
    <value>1</value>
</property>
<!-- 配置HDFS的权限检查，默认是true -->
<!--
<property>
    <name>dfs.permissions</name>
    <value>false</value>
</property>
-->

** step3:core-site.xml **
<!-- 配置HDFS主节点，namenode的地址，9000是RPC通信端口 -->
<property>
    <name>fs.defaultFS</name>
    <value>hdfs://bigdata124:9000</value>
</property>
<!-- 配置HDFS数据块和元数据保存的目录 -->
<property>
    <name>hadoop.tmp.dir</name>
    <value>/opt/moudle/hadoop-2.7.3/tmp</value>
</property>

** step4:mapred-site.xml(默认没有) **
cp mapred-site.xml.template mapred-site.xml
<!-- 配置MR程序运行的容器或框架 -->
<property>
    <name>mapreduce.framework.name</name>
    <value>yarn</value>
</property>

** step5:yarn-site.xml **
<!-- 配置Yarn的节点 -->
<property>
    <name>yarn.resourcemanager.hostname</name>
    <value>bigdata124</value>
</property>
<!-- NodeManager执行MR任务的方式是Shuffle洗牌 -->
<property>
    <name>yarn.nodemanager.aux-services</name>
    <value>mapreduce_shuffle</value>
</property>

** step6:通过HDFS namenode 格式化 **
即对第三步中的 hadoop.tmp.dir 进行格式化
# hdfs namenode -format(在/opt/moudle/hadoop-2.7.3/tmp目录下执行)

## 重复格式化hadoop.tmp.dir，必须先停止集群 # stop-all.sh，然后删除原来的tmp文件 # rm -rf /opt/moudle/hadoop-2.7.3/tmp，重新格式化 # hdfs namenode -format，最后启动集群 # start-all.sh ##
