hive与hbase数据类型对应关系

当hbase中double，int 类型以byte方式存储时，用字符串取出来必然是乱码。

在hivd与hbase整合时也遇到这个问题：做法是：#b

1.加#b

CREATE EXTERNAL TABLE hivebig (key string,CUST_NAME string,PHONE_NUM int,BRD_WORK_FLUX double)

STORED BY ‘org.apache.hadoop.hive.hbase.HBaseStorageHandler‘

WITH SERDEPROPERTIES ("hbase.columns.mapping" = ":key,bd:CUST_NAME,bd:PHONE_NUM#b,bd:BRD_WORK_FLUX#b")

TBLPROPERTIES ("hbase.table.name" = "bigtable2");

2.不加#b时，hive shell读取出来是乱码

CREATE EXTERNAL TABLE hivebig (key string,CUST_NAME string,PHONE_NUM int,BRD_WORK_FLUX double)

STORED BY ‘org.apache.hadoop.hive.hbase.HBaseStorageHandler‘

WITH SERDEPROPERTIES ("hbase.columns.mapping" = ":key,bd:CUST_NAME,bd:PHONE_NUM,bd:BRD_WORK_FLUX")

TBLPROPERTIES ("hbase.table.name" = "bigtable2");

select * FROM hivebig;

select * FROM hivebig where PHONE_NUM > 1;

select * FROM hivebig where BRD_WORK_FLUX > 1555;

cf:val#s 中的#s就表示类型为string，cf:foo没有配置类型，则采用hbase.table.default.storage.type的配置，#b为binary
