参考了很多文章，不过环境的差别导致问题也不完全相同，这里记录一下我部署的情况。
环境：腾讯云 centos7
软件版本：Hadoop 2.7.7 (后续准备上hbase2.1.5+phoenix5.0.0-HBase2.0)
部署过程网上有很多了，这里只贴我遇到的问题和配置
- core-site.xml
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<property>
<name>fs.defaultFS</name>
<value>hdfs://172.21.x.x:9000</value>
</property>
<property>
<name>hadoop.tmp.dir</name>
<value>/home/hadoop/tmp</value>
</property>
</configuration>
ps:这里注意fs.defaultFS要设置内网地址
- hdfs-site.xml
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<property>
<name>dfs.namenode.name.dir</name>

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

</configuration>
- mapred-xml
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<property>
<name>mapreduce.framework.name</name>
<value>yarn</value>

<final>true</final>
</property>
<property>
<name>mapred.local.dir</name>
<value>file:/home/hadoop/mapred/local</value>
<final>true</final>
</property>
</configuration>
- yarn-site.xml
<?xml version="1.0"?>
<configuration>
<property>
<name>yarn.nodemanager.aux-services</name>
<value>mapreduce_shuffle</value>
</property>
<property>
<name>yarn.resourcemanager.hostname</name>
<value>mytccloud</value>

<value>mytccloud:8032</value>
</property>
<property>
<name>yarn.resourcemanager.admin.address</name>
<value>mytccloud:8033</value>
</property>
<property>
<name>yarn.nodemanager.aux-services.mapreduce.shuffle.class</name>
<value>org.apache.hadoop.mapred.ShuffleHandler</value>
</property>
</configuration>
ps:这里注意 yarn.resourcemanager.webapp.address 我设置了机器名+端口，但是需要再设置host，否则可能无法启动resoucemanager
- hostname
centod7 修改hostname: hostnamectl set-hostname mytccloud
- hosts: 172.21.x.x mytccloud (也是映射到内网，将localhost的部分都注释掉)
- 目录结构
[hadoop@mytccloud hdfs]$ pwd
/home/hadoop/hdfs
