PySpark run locally on Mac: Caused by: java.io.IOException: Cannot run program "/usr/local/Cellar/apache-spark/3.0.1/libexec/bin"

I am getting this error running locally in pyCharm and tried all options:

Caused by: java.io.IOException: Cannot run program "/usr/local/Cellar/apache-spark/3.0.1/libexec/bin": error=13, Permission denied

./bash_profile: export SPARK_HOME=/usr/local/opt/apache-spark/libexec/ export PYTHONPATH=/usr/local/opt/apache-spark/libexec/python/lib/py4j-0.10.9-src.zip:/usr/local/opt/apache-spark/libexec/python/:/usr/local/lib/python3.9:$PYTHONP$ export PATH=$SPARK_HOME/bin/:$SPARK_HOME/python/lib/py4j-0.10.9-src.zip:$PATH #export PATH=$SPARK_HOME/python:$PATH

ls -lrt /usr/local/opt/apache-spark:

/usr/local/opt/apache-spark -> ../Cellar/apache-spark/3.0.1

Python Interpretor in PyCharm: /usr/local/bin/python3

In my code:

if __name__ == '__main__':
    #import os
    #import sys
    #os.environ['SPARK_HOME'] = "/usr/local/opt/apache-spark/libexec/"
    #sys.path.append("/usr/local/opt/apache-spark/libexec/python")
    #sys.path.append("/usr/local/opt/apache-spark/libexec/python/lib/py4j-0.10.9-src.zip")
    #findspark.init()
    #conf = SparkConf()
    #conf.set("fs.defaultFS", "file:///")
    spark = SparkSession.builder.master("local").appName("SyslogMaskUtility").getOrCreate()
    sc = spark.sparkContext
    #sc.setLogLevel("WARN")
    rdd_raw = sc.textFile('/Users/abcd/PycharmProjects/SyslogToJson/SyslogParser/syslog_event.txt')
    print(rdd_raw.count())
    spark.stop()

I followed: https://medium.com/beeranddiapers/installing-apache-spark-on-mac-os-ce416007d79f

and referred: Spark installation seems ok but when running program I'm having issues with environment variables. Is this .bash_profile correct?

All directories and files under /usr/local/opt/apache-spark/libexec/ have all permissions:

drwxrwxrwx   13 abcd  admin   416 Oct 29 17:34 bin

Any help please since I am struggling with this. The same code works when I run from the pyspark command line.

Thanks.

On my Mac, I install Spark and Hadoop separately

# install PySpark
pip3 install pyspark

# download and extract Hadoop 3.2.2
wget https://downloads.apache.org/hadoop/common/hadoop-3.2.2/hadoop-3.2.2.tar.gz
unzip hadoop-3.2.2.tar.gz

# setup environment variables
export JAVA_HOME='/Library/Java/JavaVirtualMachines/zulu-11.jdk/Contents/Home/'
export SPARK_DIST_CLASSPATH="hadoop-3.2.2/share/hadoop/tools/lib/*"

# run Python
python3

from pyspark.sql import SparkSession
from pyspark.sql import types as T

spark = (SparkSession
    .builder
    .master('local[*]')
    .appName('SO')
    .getOrCreate()
)
# <pyspark.sql.session.SparkSession object at 0x10f9e7220>
