> I mistakenly missed {{spark.python.profile}} enabled today while profiling and met this unfriendly messages:
> {code}
> >>> sc.show_profiles()
> Traceback (most recent call last):
>   File "<stdin>", line 1, in <module>
>   File ".../spark/python/pyspark/context.py", line 1000, in show_profiles
>     self.profiler_collector.show_profiles()
> AttributeError: 'NoneType' object has no attribute 'show_profiles'
> >>> sc.dump_profiles("/tmp/abc")
> Traceback (most recent call last):
>   File "<stdin>", line 1, in <module>
>   File ".../spark/python/pyspark/context.py", line 1005, in dump_profiles
>     self.profiler_collector.dump_profiles(path)
> AttributeError: 'NoneType' object has no attribute 'dump_profiles'
> {code}
> It looks we should give better information that says {{spark.python.profile}} should be enabled.
