I'm using version 3.2.1.
I created a node with python script to print hello world. Then created workflow and scheduled it to run in every 0th second of every minute. The execution fails with a permission denied error for some python file created and it is deleted at the end of the workflow. So, to further investigate the issue I made development.state=true in standalone-server/conf/common.properties.

This is the complete log from the execution.

Following is the content in the path /tmp/dolphinscheduler/exec/process/ishad/14374006444992/14374012970432_1/1/1

drwxr-xr-x 2 ishad ishad  80 Jul 23 15:07 .
drwxr-xr-x 3 ishad ishad  60 Jul 23 15:07 ..
-rwxr-xr-x 1 ishad ishad 161 Jul 23 15:07 1_1.sh
-rw-r--r-- 1 ishad ishad  51 Jul 23 15:07 py_1_1.py

So, it is obvious that the python script created hasn't got execution permissions. Is it a bug or do I'm missing some thing?
