嘿StackOverflowers!
我遇到了一个问题。
我已经将PyCharm设置为通过SSH连接与(自然)VM连接。
但是，当我尝试运行spark session (spark = SparkSession.builder.getOrCreate())时，databricks-connect在错误的文件夹中搜索.databricks-connect文件，并给我以下错误:

同样奇怪的是，如果我在以下位置运行:Pycharm-> ssh terminal->激活conda env-> python以下
这是一种方法:
1. Point out to java where the databricks-connect file is
2. Configure databricks-connect in another way throughout the script or enviromental variables inside pycharm
3. Other way?
or do I miss something?
最佳答案
This似乎是如何完成您想要的工作的正式教程(即databricks连接)。
您很可能是使用了错误的.databricks-connect文件版本。
您需要使用Java 8而不是11，Databricks Runtime 5.5 LTS或Databricks Runtime 6.1-6.6，并且您的python版本在两端应相同。
他们提供的步骤如下:
conda create --name dbconnect python=3.5
pip uninstall pyspark
pip install -U databricks-connect==5.5.* # or 6.*.* to match your cluster version. 6.1-6.6 are supported
databricks-connect configure
databricks-connect test
