Major Description
When running PySpark test in the local environment with "python/run-tests" command, the following error could occur.
Traceback (most recent call last): File "<string>", line 1, in <module> ... raise RuntimeError(''' RuntimeError: An attempt has been made to start a new process before the current process has finished its bootstrapping phase. This probably means that you are not using fork to start your child processes and you have forgotten to use the proper idiom in the main module: if __name__ == '__main__': freeze_support() ... The "freeze_support()" line can be omitted if the program is not going to be frozen to produce an executable. Traceback (most recent call last): ... raise EOFError EOFError
