常用操作

刷新写入磁盘

hbase(main):038:0> flush 'test'
Took 0.3084 seconds 

创建test表，至少要有一个组蔟

hbase(main):036:0> create 'test','f1'
Created table test
Took 1.3181 seconds                                                                                                                                                                                           
=> Hbase::Table - test

删除表，要先disable表在删除

hbase(main):030:0> list

获取数据

hbase(main):014:0> get 't1','0001'
COLUMN                                               CELL
