HBase基本命令

创建表    create ‘TableName’, ‘ColumnFamily’    e.g: create ‘testTable’, ‘message’ 查询表结构：    desc ‘TableName’    eg: desc ‘testTable’ 查看当先HBase中具有哪些表    list 插入数据    格式：put ‘TableName’, ‘RowKey’, ‘columnFamily’    eg:    put ‘testTable’, ‘1’, ‘message:info’ , ‘hello Hbase’    put ‘testTable’, ‘1’, ‘message:msg’ , ‘Hello Hadoop’    put ‘testTable’, ‘2’, ‘message:info’, ‘a’    put ‘testTable’, ‘2’, ‘message:msg’, ‘b’    put ‘testTable’, ‘2’, ‘message:info’, ‘c’    put ‘testTable’, ‘2’, ‘message:info1’, ‘info’

删除表: 首先禁止表， 再删除    disable ‘tableName’    drop ‘tableName’ 查询表中数据    scan ‘TableName’ 通过rowKey 获取指定行    get ‘tableName’, ‘rowKey’
