Zeppelin R 解释器无法执行任何操作

Zeppelin R interpreter fails to do anything

我正在运行ning Zeppelin 0.6.1，它的 sparkR 解释器无法执行任何操作。它在单元格执行状态上显示错误，但没有说明是什么错误。我将其二进制包与所有解释器一起使用 zeppelin-0.6.1-bin-all.tgz。尝试了很多东西，但不知道发生了什么。有人运行 Zeppelin 中的 R interpereter 成功了吗？

在日志中它显示了这个错误

我发现的是：我的 SPARK_HOME 变量设置不正确。设置它解决了问题。在另一个设置中，我虔诚地遵循了此处提到的步骤，并且效果很好。 Zeppelin R interpreter

SPARK_HOME 和 R 安装是两个主要的事情，如果正确完成应该确保在 Zeppelin 上流畅的 SparkR 体验。
