CentOS6.5中怎么通过Hadoop用户实现HDFS伪分布式部署-创新互联

这篇文章给大家介绍CentOS6.5中怎么通过Hadoop用户实现HDFS伪分布式部署，内容非常详细，感兴趣的小伙伴们可以参考借鉴，希望对大家能有所帮助。

1、检查hadoop用户是否存在

• [root@hadoop001 hadoop]# pwd

• /opt/software/hadoop-2.8.1/etc/hadoop

• [root@hadoop001 hadoop]# vim core-site.xml

• --添加,localhost修改为IP

•     

•         fs.defaultFS

•         hdfs://localhost:9000    

•     

#修改DataNode数据节点访问IP

1. [root@hadoop001 hadoop]# pwd

2. /opt/software/hadoop-2.8.1/etc/hadoop

4. [root@hadoop001 hadoop]# vim slaves

5. localhost --localhost修改为IP,多DN逗号分隔ip  

#修改SecondayNameNode数据节点访问IP

1. [root@hadoop001 hadoop]# vim hdfs-site.xml

2. -- 添加

3.     

4.         

5.                 dfs.namenode.secondary.http-address

6.                 192.168.0.129:50090

7.         

9.         

10.                 dfs.namenode.secondary.https-address

11.                  192.168.0.129:50091

12.         

13.         

14.                  dfs.replication

15.                   1

16.         

17.     

6、删除root用户的DFS文件及DFS磁盘格式化

1. [root@hadoop001 tmp]# rm -rf /tmp/hadoop-* /tmp/hsperfdata-*

2. [root@hadoop001 tmp]# su - hadoop

3. [hadoop@hadoop001 hadoop-2.8.1]$ hdfs namenode -format

7、hadoop用户启动

1. [hadoop@hadoop001 sbin]$ pwd

2. /opt/software/hadoop-2.8.1/sbin

3. [hadoop@hadoop001 sbin]$ ./start-dfs.sh       -- 第一次启动输入密码

4. Starting namenodes on [hadoop001]

5. hadoop001: starting namenode, logging to /opt/software/hadoop-2.8.1/logs/hadoop-hadoop-namenode-hadoop001.out

6. 192.168.0.129: starting datanode, logging to /opt/software/hadoop-2.8.1/logs/hadoop-hadoop-datanode-hadoop001.out

7. Starting secondary namenodes [hadoop001]

8. hadoop001: starting secondarynamenode, logging to /opt/software/hadoop-2.8.1/logs/hadoop-hadoop-secondarynamenode-hadoop001.out
