I install the newest version "databricks-connect==13.0.0". Now get the issue

@Lazloo XP​ :

The error message you received indicates that there is a problem with launching the Java gateway process. This is typically caused by a misconfiguration in the environment variables that point to the location of the Spark and Java executables.

To resolve this issue, you can try the following steps:

  1. Verify that you have installed the correct version of Java and Spark that is compatible with Databricks Connect 13.0.0.
  2. Check that the environment variables JAVA_HOME and SPARK_HOME are set correctly and point to the correct directories where Java and Spark are installed.
  3. Make sure that the bin directories of both Java and Spark are included in the PATH environment variable.
  4. Ensure that there are no conflicting versions of Java or Spark installed on your system that may be causing conflicts.

If you are still encountering issues after verifying these steps, you may want to try reinstalling Databricks Connect 13.0.0 or rolling back to version 11.3.10 if it was working previously.

Hey @Suteja Kanuri​ ,

I have no issue with version 11.3.10.. Therefore I believe that my environment variables are set correctly.

with the newest Version the error changed to
