修改方法
在hadoop namenode节点上修改hadoop2.7.7 目录
cd ~/hadoop-2.7.7/etc/hadoop/
配置
[hadoop@namenodeyw hadoop]$ cat masters
datenodeyw1 #说明 SecondaryNameNode 服务将再这台节点上启动
计算
安全
数据库
网络和加速
企业服务

依次重启服务。
先重启hadoop机器 ./start-all.sh
再重启 zookeeper ./zkSever.sh start
再到配置hbase主节点上启动habase ./start-hbase.sh
在namenode上启动
./start-all.sh 启动后进程截图
