3600 秒超时，触发工作者与心跳驱动程序中的火花驱动程序通信

Question

我没有配置任何超时值，而是使用了默认设置。在哪里配置3600秒超时？如何解决？

错误信息：

错误消息中写道：

这个超时时间由spark.executor.heartbeatInterval控制

因此，您尝试的第一件事就是增加该值。可以通过多种方式完成，例如将值增加到 10000 秒：

• 使用时spark-submit只需添加标志：

  --conf spark.executor.heartbeatInterval=10000s
  

• 您可以在spark-defaults.conf中添加一行：

  spark.executor.heartbeatInterval 10000s
  

• 在程序中创建新程序时SparkSession，添加配置参数（Scala）：

  val spark = SparkSession.builder
    .config("spark.executor.heartbeatInterval", "10000s")
    .getOrCreate()
  

如果这没有帮助，那么尝试增加 的值可能是个好主意spark.network.timeout。这也是与这些类型的超时相关的问题的常见根源。
