如何避免连续的“重置偏移”和“寻找最新偏移”？

我试着遵循以下指南：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不向控制台写入数据，为什么它会滥发执行线程日志？
我需要配置什么吗？这是我的密码：

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();
}

有时我会在控制台中获取df，但我的控制台中充满了这样的内容：

据我所知，您只想运行作业10秒，因为您正在使用中的超时 awaitTermination .
为了避免您的工作不断检查Kafka中是否有新消息可用，您可以在中设置触发器 writeStream :

.writeStream()
  .outputMode(OutputMode.Append())
  .option("checkpointLocation", "/tmp/java/checkpoint/spark")
  .trigger(Trigger.ProcessingTime("1 second")) # Alternative
  //.trigger(Trigger.Once())
  .format("console")
  .start();

这只会每秒检查Kafka中的新消息，因此每秒只会看到一次“seeking”和“reseting”日志。
你也可能对 Trigger.Once() 另一种选择。

您正在获取记录器信息，因为您已使用默认日志级别作为信息。将日志记录级别设置为警告 spark.sparkContext.setLogLevel("WARN") .
