Question

我没有配置任何超时值但使用了默认设置。在哪里配置3600秒超时？怎么解决？

错误讯息：

Answer 1

在错误消息中显示：

此超时由spark.executor.heartbeatInterval
控制

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

使用spark-submit时，只需添加标记：

--conf spark.executor.heartbeatInterval=10000s

您可以在spark-defaults.conf中添加一行：
```
spark.executor.heartbeatInterval 10000s
```

在程序中创建新的SparkSession时，添加一个配置参数（Scala）：

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

如果这没有用，那么尝试增加spark.network.timeout的值也是一个好主意。它也是与这些类型的超时相关的问题的常见来源。

Answer 2

如异常

中所述

This timeout is controlled by spark.executor.heartbeatInterval

因此，您可以使用spark.executor.heartbeatInterval来设置间隔时间，默认值为10秒。根据文档记录。

spark.executor.heartbeatInterval的Spark文档说：

每个遗嘱执行人的心跳与驾驶员之间的间隔。心跳让驱动程序知道执行程序仍处于活动状态并更新它包含正在进行的任务的指标。 spark.executor.heartbeatInterval 应该远远小于spark.network.timeout

有关详细信息，请查看spark文档here

Answer 3

val spark = SparkSession.builder().appName("SQL_DataFrame")
  .master("local")
  .config("spark.network.timeout", "600s")
  .config("spark.executor.heartbeatInterval", "10000s")
  .getOrCreate()

测试。它解决了这个问题。
