I try to add export PYSPARK_PYTHON=/home/cloudera/Python-3.6.2 in spark-env.sh
Then i run pyspark, it show /home/cloudera/Python-3.6.2 permission denied.
Thanks for reaching out. Inititally, it would seem there are some permission issues. I would start by checking the permissions for the directory the error mentions.
ls -lh /home/cloudera/Python-3.6.2
(the h is just a personal preference of mine)
Let me know what you get, and I can help from there if you'd like.
