apache-spark - Apache Spark 错误的 akka-remote netty 版本

Question

当 spark 使用 sbt 运行测试时。我得到这个异常(exception):

18:58:49.049 [sparkDriver-akka.actor.default-dispatcher-2] ERROR akka.actor.ActorSystemImpl - Uncaught fatal error from thread [sparkDriver-akka.remote.default-remote-dispatcher-5] shutting down ActorSystem [sparkDriver]

首先，我认为这是我的一个子库导入的错误版本的 netty。

查看依赖关系图后，我发现了 4 个不同版本的 netty。
3.6.6
3.8.0
3.9.3
4.0.23

论文版本大部分是spark自己导入的:o4.0.23 由 spark 直接导入，3.8.0 由其子依赖 Akka-remote

我尝试使用 excludeAll(ExclusionRule(organization = "io.netty")) 从我的所有子依赖项中排除 netty 依赖项，并逐个添加每个 netty 版本。但这并没有解决问题。我还尝试排除所有 com.typesafe.akka 部门以使用 Akka-remote 2.4.0 我遇到了同样的问题。

Akka-remote 需要的 netty 版本是 3.8.0。甚至强制这个也行不通。我还强制我的项目使用空间 Spark Akka 版本 Akka-remote:3.8.0-spark，它不会改变任何东西。

获取我的 build.sbt 的信息

Answer 1

这是一个陷阱!

netty 组织在过去发生了变化。从 org.jboss.netty 到 io.netty，但它们包含相同的包。

exclude("org.jboss.netty", "netty") 解决了我的问题。
