13GB avaliable space disabled in “df” command, but shows 50GB+ free space in “About this Mac”->“Storage”

  1. One more alternative is to set below envronment variables before start the pyspark command:

    export PYSPARK_DRIVER_PYTHON=/path/to/anacona3/bin/jupyter
    export PYSPARK_DRIVER_PYTHON_OPTS="notebook --NotebookApp.open_browser=False --NotebookApp.ip='*' --NotebookApp.port=8888"
