  2. Flink SQL Source 连接Kafka

    CREATE TABLE KAFKA_SOURCE_TBL_MEMBER_INFO_HBASE (

  3. Flink SQL Sink Hbase 需要提前在Hbase中建表

    CREATE TABLE SYNC_HBASE_SINK_TBL_MEMBER_INFO(
      rowkey STRING, 
      field ROW < `ADDRESS_STATUS` STRING,

      `CLASS_PREFER` STRING, 
      `COMMENTS` STRING, 
      `DEGRADE_SIGN` STRING, 
      `EFFECTIVE_DATE` STRING, 
      `EXPIRE_DATE` STRING, 
      `ID` STRING, 
      `INVITER_CARD_NO` STRING,

      primary key (rowkey) NOT ENFORCED
    ) WITH (
      'connector' = 'hbase-2.2', 'table-name' = 'ods:tbl_member_info', 
      'zookeeper.quorum' = '172.22.31.53:2181'
    )
    
  4. Flink SQL Dml
