Hi @zenaskun001
Could you please provide more details to check your issue.
Check the following things:
1. By default SparkInterpreter will be installed. Check in your case $ZEPPELIN_HOME/interpreters location Spark Interpreter is installed or not.
2. After proper installation, you need to restart the Zeppelin and its related Components like Spark.
3. After restarting the Zeppelin service, try to login and check the Interpreter is installed or not.
4. As a last step, you need to check the Zeppelin logs (/var/log/zeppelin) path.
