title: Why I take "spark-shell: Permission denied" error in Spark Setup?
body: <p>I am new on Apache Spark. I am trying to setup Apache Spark to my Macbook. 
   I download file "spark-2.4.0-bin-hadoop2.7" from Apache Spark official web site.<br>
  When I try to run ./bin/spark-shell or ./bin/pyspark I get <code>Permission denied error</code>.<br>
  I want to just run spark on my local machine.<br>
  I also tried to give permission to all folders but it does not help.
  Why do I this error?</p>
