结构化流+ Kafka：制作人关闭后无法发送

Question

Sparks的结构流将数据写入Kafka，并引发异常：

  

生产者关闭后无法发送。

val spark = SparkSession
  .builder()
  .appName("stream source 30361")
  .getOrCreate()

val eventSource_HS_OPT_EWB = spark
  .readStream
  .format("kafka")
  .option("kafka.bootstrap.servers", KAFKA_BOOTSTRAP_SERVERS)
  .option("subscribe", TOPIC_HS_OPT_EWB)
  .option("maxOffsetsPerTrigger", 10000)
  .option("startingOffsets", "latest")
  .option("failOnDataLoss", false) //[2018-07-13]
  .load()
  .select(from_json(col("value").cast("string"), schema_HS_OPT_EWB).alias("parsed_value"))
  .selectExpr("parsed_value.*")

eventSource_HS_OPT_EWB.createOrReplaceTempView("hsOptEwb_tl")

val exp_bol: DataFrame = spark.sql("select * from hsOptEwb_tl")

var query_exp_bol: StreamingQuery = exp_bol.selectExpr("to_json(struct(*)) AS value")
  .writeStream
  .outputMode("append")
  .format("kafka") // can be "orc", "json", "csv",memory,console etc.
  .option("kafka.bootstrap.servers", KAFKA_BOOTSTRAP_SERVERS)
  .option("topic", TOPIC_EVENT_WAYBILL)
  .option("checkpointLocation", CHECKPOINT_PATH_HS_OPT_EWB)
