执行程序心跳超时：Spark作业中发生错误

Question

我正在使用Python编程解决Spark Job中的错误。错误显示“执行器心跳超时”。错误日志如下：

Py4JJavaError: An error occurred while calling o152.parquet.

下面是错误：

原因：org.apache.spark.SparkException：作业由于阶段故障而中止：阶段9.0中的任务38失败了4次，最近一次失败：阶段9.0中的任务38.3丢失（TID 532，alp-pos-005 .unix.cosng.net，执行程序24）：ExecutorLostFailure（执行程序24退出是由于正在运行的任务之一导致）：执行程序心跳在154863 ms之后超时]

保持spark.network.timeout 10000000后，出现以下错误。

Caused by: org.apache.spark.SparkException: Job aborted due to stage failure: Task 59 in stage 19.0 failed 4 times, most recent failure: Lost task 59.3 in stage 19.0 (TID 3614, alp-pos-004.unix.cosng.net, executor 29): ExecutorLostFailure (executor 29 exited caused by one of the running tasks) Reason: Container marked as failed: container_e150_1579619385046_0042_01_000038 on host: alp-pos-004.unix.cosng.net.

在此刻，任何帮助将不胜感激。

谢谢饰面

通常，与这种情况相关的问题是内存，但是解决该问题的一种简单方法是增加spark.network.timeout。这有帮助，但这不是长期解决方案。

所以只需尝试一下：

spark-submit --conf spark.network.timeout 10000000 python_script.py
