Question

我在Spark应用程序中遇到以下异常： -

ERROR ApplicationMaster: Uncaught exception: 
java.util.concurrent.TimeoutException: Futures timed out after [100000 milliseconds]
    at scala.concurrent.impl.Promise$DefaultPromise.ready(Promise.scala:219)
    at scala.concurrent.impl.Promise$DefaultPromise.result(Promise.scala:223)

    at org.apache.spark.deploy.yarn.ApplicationMaster$.main(ApplicationMaster.scala:762)
    at org.apache.spark.deploy.yarn.ApplicationMaster.main(ApplicationMaster.scala)

这是在我的所有任务成功运行之后发生的。任务运行了大约70年代。任何人都有关于为什么会出现这样的错误的想法。这里的问题： - What are possible reasons for receiving TimeoutException: Futures timed out after [n seconds] when working with Spark，看起来因为SQL而发生了一些超时。但是，这看起来有一些网络相关的超时。

在我的Spark应用程序中获取TimeoutException
