hive 映射 hbase外部表操作

1. 示例

CREATE EXTERNAL TABLE 
default.user_regionalization(key string,uid string,followersCount int)
STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'  
WITH SERDEPROPERTIES (
"hbase.columns.mapping"=":key,
fn:uid,
fn:followersCount")
TBLPROPERTIES("hbase.table.name" = "crawl:user_regionalization");

2. 注释
   default.user_regionalization //命名空间.hive表名
   STORED BY ‘org.apache.hadoop.hive.hbase.HBaseStorageHandler’ //类似引入hbase依赖
   TBLPROPERTIES(“hbase.table.name” = “crawl:user_regionalization”); //hbase对应命名空间.表

3. 注意
   两张表的字段需要一一对应，类型可以在hive随意设置
