Hive + HBase，用HQL查询HBase

Hive整合HBase：数据实时写Hbase,实现在Hive中用sql查询

以下操作的 Hive版本：2.3.6 ,HBase版本：2.0.4

• 在HBase中创建表：t_hbase_stu_info

  create 't_hbase_stu_info','st1'

• 在Hive中创建外部表：t_hive_stu_info

  create external table t_hive_stu_info
  (id int,name string,age int,sex string)
  stored by 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'
  with serdeproperties("hbase.columns.mapping"=":key,st1:name,st1:age,st1:sex")
  tblproperties("hbase.table.name"="t_hbase_stu_info");

• 在Hbase中给t_hbase_stu_info插入数据

  put 't_hbase_stu_info','1001','st1:name','zs'
  put 't_hbase_stu_info','1001','st1:age','23'
  put 't_hbase_stu_info','1001','st1:sex','man'
  put 't_hbase_stu_info','1002','st1:name','ls'
  put 't_hbase_stu_info','1002','st1:age','56'
  put 't_hbase_stu_info','1002','st1:sex','woman'

• 查看Hbase中的数据

  scan 't_hbase_stu_info'

  

5. 查看Hive中的数据

   select * from t_hive_stu_info;
