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
test

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
hbase(main):002:0> put'test','row2','fam1:a','value' 0 row(s) in 0.3760 seconds hbase(main):003:0> put 'test','row1','fam1:a','value' 0 row(s) in 0.3760 seconds hbase(main):004:0> put 'test','row1','fam2:a','value' 0 row(s) in 0.3760 seconds hbase(main):005:0> put'test','row2','fam2:a','value' 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
hbase(main):002:0> scan 'test' ROW COLUMN+CELL row1 column=fam1:a, timestamp=1504767451331, value=value row1 column=fam2:a, timestamp=1504767471977, value=value row2 column=fam1:a, timestamp=1504767600686, value=value row2 column=fam2:a, timestamp=1504767715014, value=value 2 row(s) in 0.1120 seconds
查看指定列的数据：
hbase(main):004:0> scan 'test',{COLUMNS=> 'fam1:a'}
ROW COLUMN+CELL
row1 column=fam1:a, timestamp=1504767451331, value=value
row2 column=fam1:a,timestamp=1504767600686, value=value
2 row(s) in 0.2390 seconds
hbase(main):021:0> get 'test','row1'
COLUMN CELL
fam1:a timestamp=1504768075731, value=\x00\x00\x00\x00\x00\x00\x00\x02
fam2:a timestamp=1504767471977, value=value
2 row(s) in 0.1110 seconds
使用get查询数据：
语法：get '[namespacename:]tablename' , 'rowkey' [, 'columnfamliyname[:column]']
详细语法使用help 'get'查看
hbase(main):024:0> get'test','row1','fam1' COLUMN CELL fam1:a timestamp=1504768075731, value=\x00\x00\x00\x00\x00\x00\x00\x02 1 row(s) in 0.0690 seconds hbase(main):026:0> get 'test','row1','fam1:a' COLUMN CELL fam1:a timestamp=1504768075731, value=\x00\x00\x00\x00\x00\x00\x00\x02 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。
更详细的语法使用help 'delete'查看
hbase(main):008:0> delete'test','row1','fam1:a' 0 row(s) in 0.3370 seconds hbase(main):009:0> scan 'test' ROW COLUMN+CELL row1 column=fam2:a, timestamp=1504767471977, value=value row2 column=fam1:a, timestamp=1504767600686, value=value row2 column=fam2:a, timestamp=1504767715014, value=value 2 row(s) in 0.0850 seconds
使用incr增加数据（默认使用counter实现递增）
常用语法：incr '[namespacename:]tablename' , 'rowkey' , 'columnfamilyname:column'
更详细的语法使用help 'incr'查看
hbase(main):012:0> incr'test','row1','fam1:a' COUNTER VALUE = 1 0 row(s) in 1.1700 seconds hbase(main):013:0> scan 'test' ROW COLUMN+CELL row1 column=fam1:a,timestamp=1504768054892, value=\x00\x00\x00\x00\x00\x00\x00\x01 row1 column=fam2:a, timestamp=1504767471977, value=value row2 column=fam1:a, timestamp=1504767600686, value=value row2 column=fam2:a, timestamp=1504767715014,value=value 2 row(s) in 0.0410 seconds hbase(main):014:0> incr'test','row1','fam1:a' COUNTER VALUE = 2 0 row(s) in 0.0480 seconds hbase(main):015:0> scan 'test' ROW COLUMN+CELL row1 column=fam1:a, timestamp=1504768075731,value=\x00\x00\x00\x00\x00\x00\x00\x02 row1 column=fam2:a, timestamp=1504767471977, value=value row2 column=fam1:a, timestamp=1504767600686, value=value row2 column=fam2:a, timestamp=1504767715014, value=value 2 row(s) in 0.0770 seconds
