> The `(Series|DataFrame).describe()` in pandas API on Spark doesn't work
> properly when DataFrame has no numeric column.
>
>
> {code:java}
> >>> df = ps.DataFrame({'a': ["a", "b", "c"]})
> >>> df.describe()
> Traceback (most recent call last):
> File "<stdin>", line 1, in <module>
> File "/.../python/pyspark/pandas/frame.py", line 7582, in describe
> raise ValueError("Cannot describe a DataFrame without columns")
> ValueError: Cannot describe a DataFrame without columns
> {code}

> As it works fine in pandas, we should fix it.
