11.3.3、sql客户端

读取canal-json的数据到hbase中
（1）导包

    org.apache.flink
    flink-connector-hbase_2.11
    1.11.2

（2）代码实现

object Demo10toHbase {
  def main(args: Array[String]): Unit = {

    val bsEnv = StreamExecutionEnvironment.getExecutionEnvironment
    val bsSettings = EnvironmentSettings
      .newInstance()
      .useBlinkPlanner() //使用blink的计划器
      .inStreamingMode() //使用流模型
      .build()

    //窗口table 环境
    val bsTableEnv: StreamTableEnvironment = StreamTableEnvironment.create(bsEnv, bsSettings)
//    val configuration = new Configuration()
//    //如果主键为null,自动删除
//    configuration.setString("table.exec.sink.not-null-enforcer", "drop")
//    configuration.setString("table.dynamic-table-options.enabled", "true")
//    bsTableEnv.getConfig.addConfiguration(configuration)
