Flink SQL将group聚合的数据写入到HBase表报primary keys问题
各位好，
最近在研究Flink Hbase连接器，测试实验是将聚合的数据写入到hbase报错。希望能得到各位的帮助。代码 如下：
/**
* @Author: ellis.guan
* @Description: HBase测试类
* @Date: 2020/3/6 15:41
* @Version: 1.0
*/
public class HbaseTest {
private StreamExecutionEnvironment env;
private StreamTableEnvironment tableEnv;
@Before
public void init(){
env=StreamExecutionEnvironment.getExecutionEnvironment();
EnvironmentSettings settings = EnvironmentSettings.newInstance().useBlinkPlanner().inStreamingMode().build();
tableEnv = StreamTableEnvironment.create(env, settings);
tableEnv.sqlUpdate("create table resume01(\n" +
" `rowkey` string,sdp_columns_family ROW<age string,mobile BIGINT> \n" +
// " `binfo` ROW<age string,mobile string,site string>,\n" +
// " edu ROW<university string>, \n" +
// " work ROW<company1 string> \n" +
") with (" +
" 'connector.type' = 'hbase', " +
" 'connector.version' = '1.4.3', " +
" 'connector.table-name' = 'resume01'," +
" 'connector.zookeeper.quorum' = 'localhost:2181'," +
" 'connector.zookeeper.znode.parent' = '/hbase'" +
")");
}
@Test
public void testReadFromHBase() throws Exception {
// HBaseTableSource resume = new HBaseTableSource();
Table table = tableEnv.sqlQuery("select * from resume");
DataStream<Tuple2<Boolean, Row>> out = tableEnv.toRetractStream(table, Row.class);
out.print();
env.execute();
}
@Test
public void testWriterToHBase() throws Exception {
DataStream<Row> source = env.fromElements(
Row.of("ellis","2015-03-27","17352837822","changsha","hun nan","shiji"),
Row.of("ellis","2015-03-28","17352837825","changsha1","hun nan","shiji"),
Row.of("ellis","2015-03-279","17352837826","changsha2","hun nan","shiji"));
tableEnv.createTemporaryView("source_resume",source,"name,age,mobile,site,university,company1");
tableEnv.sqlUpdate("insert into resume01 select CONCAT_WS('_',age,name),ROW(age,mobile) from " +
" (select name,age,sum(cast(mobile as bigint)) as mobile from source_resume group by name,age ) as tt");
env.execute();
}
}
运行报错如下：

Re: Flink SQL将group聚合的数据写入到HBase表报primary keys问题
Posted by Jark Wu <im...@gmail.com>.
Hi,
目前 Flink SQL 在插入数据到数据库时，要求 query 的 key 与结果表的 key 相同。这里 HBase 的 key 一直都是
rowkey，但是 query 的 key 丢失了（concat_ws 丢失了 key 属性），因此需要直接 group by
concat_ws(..)，才能获得 key 且对应上 HBase 的 rowkey。所以你的 query 需要改成这样：
insert into resume01
select age_name,ROW(age,mobile)
from (
select CONCAT_WS('_',age,name) as age_name,sum(cast(mobile as bigint))
as mobile
from source_resume group by CONCAT_WS('_',age,name)
) as tt
Best,
Jark
