配置文件:(conf/backup-masters )(配置的是二哥，大哥挂掉，二哥顶上)(复制的regionservers 新建的)

node7-1node7-3

配置文件:(conf/hbase-site.xml )(配置的是小弟)

      			检查兼容性,如果设置为false,数据有可能丢失(这是一个警告)		  Controls whether HBase will check for stream capabilities (hflush/hsync).		  Disable this if you intend to run on LocalFileSystem, denoted by a rootdir		  with the 'file://' scheme, but be mindful of the NOTE below.		  WARNING: Setting this to false blinds you to potential data loss and		  inconsistent system state in the event of process and/or node failures. If		  HBase is complaining of an inability to use hsync or hflush it's most		  likely not a false positive.

配置文件:(conf/hbase-env.sh )

配置jdk路径，将hbase自带的zookeeper关掉

在想当大哥的服务器启动hbase;(node7-2)

bin/start-hbase.sh

关掉

bin/stop-hbase.sh

访问

http://node7-2:16010/

注：1.因为Hbase连接hadoop是通过hdfs协议的,所有hadoop的配置文件是无法读取的;
