hive与hbase关联

进入hbase: hbase shell
进入HIVE: hive

hbase中建一张t_student_info表，添加两个列族
create 't_student_info','st1','st2'

hbase查看表结构
describe 't_student_info'



hive 创建外部表要使用EXTERNAL 关键字
create external table t_student_info(
     id int
    ,age int
    ,sex string
) 
stored by 'org.apache.hadoop.hive.hbase.HBaseStorageHandler' 
with serdeproperties("hbase.columns.mapping"=":key,st1:age,st2:sex") 
tblproperties("hbase.table.name"="t_student_info")
;


hbase t_student_info 中添加数据
put 't_student_info','1001','st2:sex','man'
put 't_student_info','1001','st1:age','20'
put 't_student_info','1002','st1:age','18'
put 't_student_info','1002','st2:sex','woman'

hive 数据查询
select * from t_student_info;
