java - 如何避免连续出现 "Resetting offset"和 "Seeking to LATEST offset"？

Question

我正在尝试遵循本指南: https://spark.apache.org/docs/latest/structured-streaming-kafka-integration.html但我不明白为什么我大部分时间都没有向控制台写入数据，为什么它的垃圾邮件执行线程日志记录？
我需要配置什么吗？这是我的代码:

SparkSession spark = SparkSession
  .builder()
  .appName("Testing")
  .config("spark.master", "local")
  .getOrCreate();

StructType recordSchema = new StructType()
  .add("description", "string")
  .add("location", "string")
  .add("id", "string")
  .add("title", "string")
  .add("company", "string")
  .add("place", "string")
  .add("date", "string")
  .add("senorityLevel", "string")
  .add("function", "string")
  .add("employmentType", "string")
  .add("industries", "string");

Dataset<Row> df = spark
  .readStream()
  .format("kafka")
  .option("kafka.bootstrap.servers", "127.0.0.1:9092")
  .option("subscribe", "linkedin-producer")
  .option("startingOffsets", "earliest")
  .option("kafka.group.id","test")
  .load();

StreamingQuery query = df
  .selectExpr("CAST(key AS STRING)", "CAST(value AS STRING)")
  .select(from_json(col("value").cast("string"), recordSchema).as("data"))
  .select("data.*")
  .writeStream()
  .outputMode(OutputMode.Append())
  .format("console")
  .start();

try {
  query.awaitTermination(10000);
} catch (StreamingQueryException e) {
  e.printStackTrace();
}

有时我在控制台中得到 df，但我的控制台充满了这个:
