我有一个具有Akka依赖关系的超级jar,我试图在Apache Toree上使用Spark(通过将spark-defaults.conf
设置为spark.jars
,通过/home/cdsw/uber.jar
添加)。 Toree有自己的内部版本的Akka,它与超级罐子不同(超级jar = 2.5.11,Toree = 2.3.4)。为了解决这个版本的冲突,我试图遮蔽优步版的Akka,但仍然收到以下错误。我相信这是因为在超级罐中有一个reference.conf
文件,而在Toree中有一个文件,而且这些文件不会相互粘合。

我最初假设有关冲突的conf文件是否正确?如果是这样,是否可以通过sbt分离这些域?
该项目依赖于"com.typesafe.play" % "play-ws-standalone-json_2.11" % "2.0.0-M1"
,内部Akka版本是依赖项。
