Question

我想寻求与Anaconda Jupyter笔记本相关的帮助。我想在Jupyter笔记本中编写PySpark和SparkR，然后我按照在线教程教授如何与Jupyter笔记本一起安装Apache Toree。

我正在使用Cloudera Manager parcel来管理我的kerberized Hadoop集群。

但是，我无法在服务器日志中使用以下错误打开Apache Toree PySpark的内核。

我已将jopt-simple-4.5.jar放入Toree lib和Spark home。有什么地方我必须把罐子放在那里，以便它可以在尝试创建新笔记本时找到它？感谢。

祝你好运，鲁卡

我找到的最简单的解决方案是将以下选项添加到spark-submit：

--conf "spark.driver.extraClassPath=/usr/local/share/jupyter/kernels/apache_toree_scala/lib/toree-assembly-0.1.0-incubating.jar" --conf "spark.executor.extraClassPath=/usr/local/share/jupyter/kernels/apache_toree_scala/lib/toree-assembly-0.1.0-incubating.jar"

可以将其添加到__TOREE_SPARK_OPTS__文件的/usr/local/share/jupyter/kernels/apache_toree_scala/kernel.json变量中，也可以直接添加到/usr/local/share/jupyter/kernels/apache_toree_scala/bin/run.sh文件中的bash命令。

通过添加这个，你强制类加载器从Toree JAR加载joptsimple.OptionParser而不是从默认的CDH库加载。{/ p>

P上。 S.这是与CDH 5.10.0兼容的Toree版本：https://github.com/Myllyenko/incubator-toree/releases
