I am running a problem when I try to call pyspark in Apache Zeppelin, see below.
Apache Zeppelin Version 0.8.0 Spark 2.3.0 (git revision a0d7949896) built for Hadoop 2.7.3 Python 3.6.4 OpenJDK Runtime Environment (build 1.8.0_161-b14) OpenJDK 64-Bit Server VM (build 25.161-b14, mixed mode)
I added in zeppelin-env.sh.
export PATH=$PATH:/usr/local/scala/bin
export PATH=$PATH:/usr/local/spark/bin
export SPARK_HOME=/usr/local/spark
Zeppelin notebook
%pyspark
