FileNotFoundError while downloading wikipedia dataset for any language
Hi @Shilpac20,

As explained in the Wikipedia dataset card: https://huggingface.co/datasets/wikipedia
> You can find the full list of languages and dates [here](https://dumps.wikimedia.org/backup-index.html).

This means that, before passing a specific date, you should first make sure it is available online, as Wikimedia only keeps last X months (depending on the size of the corresponding language dump)): e.g. to see which dates "aa" Wikipedia is available online, see https://dumps.wikimedia.org/aawiki/ (as of today 2022-08-31, the available dates are from [20220401](https://dumps.wikimedia.org/aawiki/20220401/) to [20220820](https://dumps.wikimedia.org/aawiki/20220820/)). Hi, the date that I have specified "20220401" is available for the language "aa". The error persists for any other available dates as present in https://dumps.wikimedia.org/aawiki/. The error is mainly due to apache beam not able to write the downloaded files. Any help on this? I see, sorry, I misread your issue.

We are investigating this. I am struggling with basically the same issue. I am trying to download the German Wikipedia dump.

As per the [documentation](https://huggingface.co/datasets/wikipedia), `"20220301.de"` should be available as a pre-processed dataset.

Issuing the command mentioned in the documentation cited above

    from datasets import load_dataset
    load_dataset("wikipedia", "20220301.de")

raises the following `FileNotFound` error

    FileNotFoundError: Couldn't find file at https://dumps.wikimedia.org/dewiki/20220301/dumpstatus.json

Using the ([undocumented](https://huggingface.co/docs/datasets/v1.2.1/package_reference/loading_methods.html#datasets.load_dataset)?) call to `load_dataset()` with `language` and `date` parameters

    load_dataset("wikipedia", language="de", date="20220301", beam_runner="DirectRunner")

produces the same error.

EDIT: as I am using `datasets` v2.7.1, I should be looking at [that version's documentation](https://huggingface.co/docs/datasets/v2.7.1/en/package_reference/loading_methods#datasets.load_dataset)! It is mentioned there, that additional `kwargs` are "passed to the [BuilderConfig](https://huggingface.co/docs/datasets/v2.7.1/en/package_reference/builder_classes#datasets.BuilderConfig) and used in the [DatasetBuilder](https://huggingface.co/docs/datasets/v2.7.1/en/package_reference/builder_classes#datasets.DatasetBuilder)". So I guess that is how `language` and `date` are used.

As I can see a folder `20221130` on `https://dumps.wikimedia.org/dewiki/`, I also tried

    from datasets import load_dataset
    load_dataset("wikipedia", "20221130.de")

which throws another error:

    ValueError: BuilderConfig 20221120.de not found. Available: ['20220301.aa', ... '20220301.de', ...

basically telling me that the dataset I originally requested (`'20220301.de'`) is available...

It seems that `load_dataset` is not handling the vanishing older dumps for Wikipedia correctly? I am able to start downloading the dataset when trying anything with the recent dumps for 20221201. But obviously, those are the big wiki dumps and I need the smaller preloaded version.

I am now getting some error when the files show up in my cache but it will say FileNotFoundError at the end of the download for some reason. The cache directory to the datasets\wikipedia\date.bn\ had something in it, then when the error came up it disappeared. 

It is easy to test with the langauge "bn" because the amount of files is low.

dataset = load_dataset('wikipedia', date="20221201", language="bn", split='train', beam_runner='DirectRunner')
## Describe the bug
Hi, I am currently trying to download wikipedia dataset using  
load_dataset("wikipedia", language="aa", date="20220401", split="train",beam_runner='DirectRunner'). However, I end up in getting filenotfound error.  I get this error for any language I try to download.


Environment:


## Steps to reproduce the bug
```python
from datasets import load_dataset
load_dataset("wikipedia", language="aa", date="20220401", split="train",beam_runner='DirectRunner')
```

## Expected results
to load the dataset

## Actual results
