I've installed spark on my Mac and everything works fine when I run a spark-submit job in terminal or when I use spark-shell. I also installed Zeppelin, but when I try running a simple sc in a Zeppelin notebook I get the following error.

Versions:
- Zeppelin: 0.8.0
- Scala: 2.12.8
- Spark: 2.3.2
- Java: 11.0.2
3 things I included in zeppelin-env.sh:
- export PYTHONPATH=/usr/bin/python
- export SPARK_HOME=/usr/local/Cellar/apache-spark/2.3.2/libexec
- export HADOOP_CONF_DIR=/usr/local/bin/hadoop
Does anyone know what might be missing here?
