When I tried running the command below on the Juypter:

 spark=SparkSession.builder.appName('Practise').getOrCreate()

It gives this error:

 RuntimeError: Java gateway process exited before sending its port number

I did the checking on the anaconda prompt

**Manage to resolve it by restarting the ananconda. The error is resolved though it states warning her and there.

Input:

 java --version

Output:

java 21.0.4 2024-07-16 

Input:

javac --version

Output:

javac 21.0.4

Input:

echo $JAVA_HOME

Output:

$JAVA_HOME
 

What possibility that I haven’t done. I have also created the environment variable and added the java path to it. Thanks
