Apache Toree 与 Anaconda Jupyter Notebook

Question

我想寻求与 Anaconda Jupyter notebook 相关的帮助。我想在 Jupyter notebook 中编写 PySpark 和 SparkR，我按照在线教程教如何将 Apache Toree 与 Jupyter notebook 一起安装。

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

但是，我无法打开 Apache Toree PySpark 的内核，并在服务器日志中显示以下错误。

我已将 jopt-simple-4.5.jar 放在 Toree 库和 Spark 主页中。有没有什么地方我必须把罐子放在那里，以便在尝试创建新笔记本时可以找到它？谢谢。

最好的问候， 卢卡

Answer 1

我找到的最简单的解决方案是在 spark-submit 中添加以下选项：

--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"

这可以添加到/usr/local/share/jupyter/kernels/apache_toree_scala/kernel.json 文件的__TOREE_SPARK_OPTS__ 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 命令中。

通过添加此选项，您将强制类加载器从 Toree JAR 加载 joptsimple.OptionParser，而不是从默认 CDH 库加载。

P。 S. 这是一个与 CDH 5.10.0 兼容的 Toree 版本：https://github.com/Myllyenko/incubator-toree/releases
