1 Introduction
利用restapi来获取hbase的数据

2 Configure
2.1 version
命令：curl http://10.1.200.7:8080/version

2.2 获取集群信息
命令：curl -H “Accept:application/json” http://10.1.200.7:8080/version/cluster

2.3 获取集群中各个实例的状态
命令：curl -H “Accept:application/json” http://10.1.200.7:8080/status/cluster

2.4 获取所有的table信息
命令：curl http://10.1.200.7:8080/

2.5 获取某一个表的建表信息
命令： curl -H “Accept:application/json” http://10.1.200.7:8080/tablename/schema

Postscript:

创建表： put /tablename/schema
更新表： pos /tablename/schema
删除表： DELETE /tablename/schema
2.6 获取表的metadata数据
命令：curl -H “Accept:application/json” http://10.1.200.7:8080/basic-test/regions

3 Rest Method
GET 根据content-type获取指定格式的数据
PUT 根据content-type以及对应格式的数据，替换hbase上已经存在的数据
POST 添加数据到hbase上
DELETE 删除hbase上的数据
4 Get
4.1 Format

path := '/' <table> 
        '/' <row> 
        ( '/' ( <column> ( ':' <qualifier> )? 
                ( ',' <column> ( ':' <qualifier> )? )+ )? 
            ( '/' ( <start-timestamp> ',' )? <end-timestamp> )? )? 
query := ( '?' 'v' '=' <num-versions> )?
4.2 Intro
table # 表格名
row # rowkey键值
column # 列名，可以是正则通配符来进行范围获取
qualifier # 列名对应的修饰符
timestamp # 指示版本信息
4.3 获取多keys上相同的column:qualifier
命令： curl -H “Accept:application/json” http://10.1.200.7:8080/basic-test/devops-dev1:2015092603*/cpu:used|python -m json.tool

4.4 获取某一个小时内33分钟~36分钟的所有所有数据
命令： curl -H “Accept:application/json” http://10.10.116.229:8080/basic/dm-positionrec-python-bja-001:20150930173[3-6]

5 PUT
5.1 Format
path := '/' <table> '/' <row> '/' <column> ( ':' <qualifier> )? 
          ( '/' <timestamp> )? 
# 或者
path := '/' <table> '/' <false-row-key>
5.2 Intro
false-row-key # 一次put多个keys，直接在url后面写入false-row-key即可

5.3 存入列信息到指定的table, rowkeys中
附录：存在就覆盖，不存在添加，其他都不变

命令:

curl -v -X PUT -H "Content-Type: application/json" --data '{"Row":[{"Cell":[{"column":"YWdlOg==","timestamp":1443555518104,"$":"MjQ="},{"column":"Y29sb3I6","timestamp":1443555530473,"$":"cmVk"}],"key":"d2hvOjAx"}]}' http://10.1.200.7:8080/bifeng/who:01
返回：200

5.4 存入多行信息到指定的table中
命令：

curl -v -X PUT -H "Content-Type: application/json" --data '{"Row":[
     {"Cell":[
          {"column":"YWdlOg==","$":"MjQ="},
          {"column":"Y29sb3I6","$":"cmVk"},
          {"column":"bmFtZTo=","$":"bXlsb3Zl"}
          ],
     "key":"cGFueGlhb3l1YW46MDE="
     },
     {"Cell":[
          {"column":"YWdlOg==","$":"Mjc="},
          {"column":"Y29sb3I6","$":"Ymx1ZQ=="},
          {"column":"bmFtZTo=","$":"bG92ZQ=="}
          ],
     "key":"d2hvOjAx"}
]}' http://10.1.200.7:8080/bifeng/false-row-key
返回：200

注意: 在退出数据时，key必须在cell的前头

6 构建http的请求体
必须保证每一个column的格式为ABC:xxx，其中xxx可以不存在, 通过”Content-Type: application/json”或者其他值来指定请求体中的数据编码形式;

curl命令:

curl -v -X PUT -H "Content-Type: application/json" --data '{"Row":[{"Cell":[{"column":"YWdlOg==","timestamp":1443555518104,"$":"MjQ="},{"column":"Y29sb3I6","timestamp":1443555530473,"$":"cmVk"},{"column":"bmFtZTo=","timestamp":1443555541777,"$":"bG92ZQ=="}],"key":"d2hvOjAx"}]}' http://10.1.200.7:8080/bifeng/who:01
