I met with the same error when I used scala-library-2.11 jar But when I replaced it with scala-library-2.10 jar . It runs fine
我在使用 scala-library-2.11 jar 时遇到了同样的错误但是当我用 scala-library-2.10 jar 替换它时。它运行良好
回答by Guido
It is probably caused by using incompatible versions of Scala. When I downgraded from Scala 2.11 to 2.10, I forgot to modify one package version (so one package used 2.11, the rest 2.10), resulting in having the same error.
这可能是由于使用了不兼容的 Scala 版本造成的。当我从Scala 2.11降级到2.10时，我忘记修改一个包版本（所以一个包使用了2.11，其余的2.10），导致出现同样的错误。
Note: I only had this problem when using IntelliJ.
注意：我只在使用 IntelliJ 时遇到过这个问题。

If you are getting the error and here because you cannot run Jupiter notebooks with Spark 2.1 and Scala 2.11 below is how I was able to make it work. Assumes you installed Jupiter and toree
如果您收到错误，并且因为您无法使用下面的 Spark 2.1 和 Scala 2.11 运行 Jupiter 笔记本，那么我是如何让它工作的。假设您安装了 Jupiter 和 toree
Pre-req- Make sure Docker is running else Make fails. Make sure gpg is installed else Make fails.
Pre-req- 确保 Docker 正在运行，否则 Make 失败。确保安装了 gpg，否则 Make 失败。

Check whether the scala version you are using corresponds to the precompiled spark version.
检查您使用的 scala 版本是否与预编译的 spark 版本相对应。

The issue could be reproduced with version 2.11.8.
该问题可以通过版本重现2.11.8。
By the moment, no downgrade is required.
Just update scala-libraryversion to 2.12.0.
目前，不需要降级。只需将scala-library版本更新到2.12.0。

I've the same issue but where do i alter the scala-library version?
我有同样的问题，但我在哪里更改 scala-library 版本？
Installation (on Ubuntu 16.04):
安装（在 Ubuntu 16.04 上）：
sudo apt-get install oracle-java8-installer
wget http://d3kbcqa49mib13.cloudfront.net/spark-2.0.2-bin-hadoop2.7.tgz && tar xvf spark-2.0.2-bin-hadoop2.7.tgz
pip install toree && jupyter toree install
So when I start with a notebook it tells me that I use a different scala version. But I haven't installed anything else. screenshot + scala version
所以当我开始使用笔记本时，它告诉我我使用的是不同的 Scala 版本。但我还没有安装其他任何东西。 屏幕截图 + Scala 版本
My spark jars folder contains an scala-library-2.11.8.jarfile. But how tell torree to use that (or another) file for scala.
我的 spark jars 文件夹包含一个scala-library-2.11.8.jar文件。但是如何告诉 torree 将那个（或另一个）文件用于 scala。

我遇到了完全相同的问题，并通过将 Scala 2.11.8 降级到 2.10.6 来解决它。
