单机部署Hadoop
系统环境如下：
OS : Ubuntu 15.10
Hadoop : 2.7.1
JAVA:1.8.66
本文只记录Hadoop的部署，与之相关的请自行百度，
将hadoop-2.7.1.tar.gz 解压到/home/hadoop 下面
tar xvzf hadoop-2.7.1.tar.gz
配置文件都在Hadoop的etc/hadoop下。
配置 core-site.xml
<configuration>
<property>
<name>fs.defaultFS</name>
<value>hdfs://hdp-1:9000</value>
</property>
<property>
<name>hadoop.tmp.dir</name>
<value>/home/hadoop/hadoop-2.7.1/hadoop_tmp</value>
<description>namenode tmp</description>
</property>
<property>
<name>io.file.buffer.size</name>
<value>65535</value>
</property>
</configuration>修改hosts文件
增加 hdp-1
在 /home/hadoop/hadoop-2.7.1/新建一个hadoop_tmp文件夹
修改hdfs-site.xml
<configuration>
<property>
<name>dfs.replication</name>
<value>1</value>
</property>
</configuration>运行格式化命令：
bin/hdfs namenode -format出现下图信息：
