Hadoop全分布部署
Hadoop集群验证
使用jps查看各个节点启动的进程情况
[hadoop@master ~]$ jps
2224 ResourceManager
2487 Jps
2059 SecondaryNameNode
1852 NameNode
[hadoop@slave1 ~]$ jps
1702 NodeManager
1897 Jps
1612 DataNode
[hadoop@slave2 ~]$ jps
1641 DataNode
1899 NodeManager
2027 Jps
查看Hadoop的web监控页面
http://master:50070 或 http://10.10.10.128:50070 查看NameNode节点启动正常
http://master:8088 或 http://10.10.10.128:8088 查看所用应用系统启动正常
使用Hadoop命令关闭集群
[hadoop@master ~]$ stop-all.sh
This script is Deprecated. Instead use stop-dfs.sh and stop-yarn.sh
Stopping namenodes on [master]
