hbase(main):005:0> table_help
Help for table-reference commands.
You can either create a table via 'create'and then manipulate the table via commands like 'put', 'get', etc.
See the standard help information for howto use each of these commands.
…创建表
常用语法：create '[namespacename:]tablename' [ ,'columnfamilyname1' [ ,'columnfamilyname2, ....]]
详细语法使用help -create 查看create语句
hbase(main):006:0> create 'test','fam1','fam2'
0 row(s) in 8.3530 seconds
=> Hbase::Table – test使用list命令列出表名：
常用语法：list '[namespacename:]tablename]
详细语法可以使用help 'list' 查看，list 后面可以跟正则表达式，列出符合表达式的表名
hbase(main):011:0> list 'test' –列出名为test的表名
TABLE
test
1 row(s) in 0.0110 seconds
=> ["test"]
hbase(main):012:0> list 'tes.*'—列出以名称tes开头的表名
TABLE
test
test:testtable
2 row(s) in 0.0150 seconds
=> ["test","test:testtable"]
hbase(main):013:0> list 'default:.*' –列出default命名空间下的表名
TABLE
ambarismoketest
test
2 row(s) in 0.0150 seconds
=> ["ambarismoketest","test"]
hbase(main):014:0> list 'test:.*' –列出test这个命名空间下的表名
TABLE
test:testtable
1 row(s) in 0.0140 seconds
=> ["test:testtable"]使用desc命令查看指定表的具体信息（desc等同于describe）
语法：desc '[namespacename:]tablename'
describe '[namespacename:]tablename'
详细语法使用help 'describe'查看
hbase(main):016:0> desc 'test' 查看test这张表的信息
Table test is ENABLED

3 row(s) in 0.0290 seconds使用put插入数据
常用语法：put '[namespacename:]tablename' , 'rowkey' , 'columnfamilyname[:column]' , 'value'
详细语法使用help 'put'查看

0 row(s) in 0.3760 seconds使用scan查看全表数据
常用语法：scan '[namespacename:]tablename'
详细语法使用help 'scan'查看

1 row(s) in 0.0430 seconds使用delete删除数据
常用语法：delete '[namespacename:]tablename' , 'rowkey' , 'columnfamliyname:column'
当表中存在只制定了columnfamily没有具体制定column的数据时，delete可以这么用
delete '[namespacename:]tablename' , 'rowkey' , 'columnfamliyname',不存在这样的数据，使用这样的语句不会删除数据。
