在Apache Spark中。 如何设置worker / executor的环境变量？

我的EMR火花程序不断收到此错误：

我做了一些调查，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

但是我只能使用spark-submit.sh --conf来设置它，它只影响驱动程序，而大部分错误都在工人身上。

有没有办法将它们传播给工人？

非常感谢。

刚刚在Spark文档中偶然发现了一些东西：

spark.executorEnv.[EnvironmentVariableName]

将由EnvironmentVariableName指定的环境变量添加到Executor进程。 用户可以指定其中的多个来设置多个环境变量。

所以在你的情况下，我会设置Spark配置选项spark.executorEnv.com.amazonaws.sdk.disableCertChecking为true ，看看是否有帮助。
