I'm very new to PySpark, I'm trying to execute the pyspark command in my anaconda prompt then it popped out many warnings that I'm confused of or which warning should I really care that could be future problems. Is there any way to fix these? I'm afraid these warnings will cause future errors when I'm trying to learn PySpark on my jupyter notebook..
