我已经在我的远程Linux服务器（IBM RHEL Z系统）上配置了Spark 2.1。我正在尝试创建一个SparkContext并收到以下错误
from pyspark.context import SparkContext, SparkConf
master_url="spark://<IP>:7077"
conf = SparkConf()
conf.setMaster(master_url)
conf.setAppName("App1")
sc = SparkContext.getOrCreate(conf)
我收到以下错误。 当我在 PySpark 外壳中的远程服务器上运行相同的代码时，它可以正常工作。
The currently active SparkContext was created at:
(No active SparkContext.)

听起来你还没有将jupyter设置为pyspark驱动程序。在从 jupyter 控制 pyspark 之前，您必须首先设置 PYSPARK_DRIVER_PYTHON=jupyter 并PYSPARK_DRIVER_PYTHON_OPTS='notebook' 。如果我没记错的话，如果您查看libexec/bin/pyspark中的代码（在OSX上），您将找到设置jupyter笔记本的说明。
