我在 EMR 上的 spark 程序不断收到此错误:

我做了一些研究，发现可以通过设置环境变量在低安全性情况下禁用此身份验证:
com.amazonaws.sdk.disableCertChecking=true
但我只能用 spark-submit.sh --conf 设置它，它只影响驱动程序，而大多数错误都发生在 worker 身上。
有没有办法将它们传播给 worker ？
非常感谢。
最佳答案
刚刚在 Spark documentation 中偶然发现了一些东西:spark.executorEnv.[EnvironmentVariableName]
Add the environment variable specified by EnvironmentVariableName to the Executor process. The user can specify multiple of these to set multiple environment variables.
所以在你的情况下，我会设置 Spark 配置选项
spark.executorEnv.com.amazonaws.sdk.disableCertChecking至 true看看这是否有帮助。
关于amazon-web-services - 在 Apache Spark 中。如何设置worker/executor的环境变量？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/29354077/
