创建Hbase维表

功能描述

创建Hbase维表用于与输入流连接。

前提条件

  • 该场景作业需要运行在DLI的独享队列上,因此要与HBase建立增强型跨源连接,且用户可以根据实际所需设置相应安全组规则。
  • 若使用MRS HBase,请在增强型跨源的主机信息中添加MRS集群所有节点的主机ip信息。

    详细操作请参考《数据湖探索用户指南》中的“修改主机信息”章节描述。

语法格式

create table hbaseSource (
  attr_name attr_type 
  (',' attr_name attr_type)* 
 )
with (
  'connector.type' = 'hbase',
  'connector.version' = '1.4.3',
  'connector.table-name' = '',
  'connector.zookeeper.quorum' = ''
);

参数说明

表1 参数说明

参数

是否必选

说明

connector.type

connector的类型,只能为hbase

connector.version

该值只能为1.4.3

connector. table-name

hbase中的表名

connector.zookeeper.quorum

Zookeeper的地址

connector.zookeeper.znode.parent

Zookeeper中的根目录,默认是/hbase

示例

create table hbaseSource(
  id string,
  i Row<score string>
 ) with (
   'connector.type' = 'hbase',
   'connector.version' = '1.4.3',
   'connector.table-name' = 'user',
   'connector.zookeeper.quorum' = 'xxxx:2181'
 );
create table source1(
  id string,
  name string,
  geneder string,
  age int,
  address string,
  proctime as PROCTIME()
) with (
  "connector.type" = "dis",
  "connector.region" = "cn-north-7",
  "connector.channel" = "read",
  "connector.ak" = "xxxxxx",
  "connector.sk" = "xxxxxx",
  "format.type" = 'csv'
);

 create table hbaseSink(
  rowkey string,
  i Row<name string, geneder string, age int, address string>,
  j ROW<score string>
 ) with (
   'connector.type' = 'hbase',
   'connector.version' = '1.4.3',
   'connector.table-name' = 'score',
   'connector.write.buffer-flush.max-rows' = '1',
   'connector.zookeeper.quorum' = 'xxxx:2181'
 );
 insert into hbaseSink select d.id, ROW(name, geneder,age,address), ROW(score) from source1 as d join hbaseSource for system_time as of d.proctime as h on d.id = h.id;
