flink1.9 blink planner table ddl 使用问题

flink1.9 blink planner table 使用ddl 语句,创建表不成功,不知道是少了 定义属性还是 需要实现TableSourceFactory,还是其他什么.

提示: Exception in thread "main" org.apache.flink.table.api.ValidationException: SQL validation failed. findAndCreateTableSource failed. Caused by: org.apache.flink.table.api.NoMatchingTableFactoryException: Could not find a suitable table factory for 'org.apache.flink.table.factories.TableSourceFactory' in the classpath.

代码:

import org.apache.flink.streaming.api.scala.{StreamExecutionEnvironment, _}
import org.apache.flink.table.api.{EnvironmentSettings, Types}
import org.apache.flink.table.api.scala.{StreamTableEnvironment, _}
import org.apache.flink.types.Row


object KafkaInDDL extends App {
val env = StreamExecutionEnvironment.getExecutionEnvironment
val settings: EnvironmentSettings = EnvironmentSettings.newInstance().useBlinkPlanner().inStreamingMode().build()
val tEnv: StreamTableEnvironment = StreamTableEnvironment.create(env, settings)


val sourceDDL =
"""create table sourceTable(
id int,
name varchar
) with (
'connector.type' = 'kafka',
'connector.property-version' = '1',
'update-mode' = 'append',
'bootstrap.servers' = '192.168.1.160:19092',
'connector.topic' = 'hbtest1',
'connector.startup-mode' = 'earliest-offset'
)
"""
tEnv.sqlUpdate(sourceDDL)
tEnv.sqlQuery("select * from sourceTable").toAppendStream[Row].print()
tEnv.execute("")
}
