load_dataset() cannot find dataset_info.json with multiple training runs in parallel
Hi ! It fails because the dataset is already being prepared by your first run. I'd encourage you to prepare your dataset before using it for multiple trainings.

You can also specify another cache directory by passing `cache_dir=` to `load_dataset()`. Thank you! What do you mean by prepare it beforehand? I am unclear how to conduct dataset preparation outside of using the `load_dataset` function. You can have a separate script that does load_dataset + map + save_to_disk to save your prepared dataset somewhere. Then in your training script you can reload the dataset with load_from_disk Thank you! I believe I was running additional map steps after loading, resulting in the cache conflict. 
### Describe the bug

I have a custom local dataset in JSON form. I am trying to do multiple training runs in parallel. The first training run runs with no issue. However, when I start another run on another GPU, the following code throws this error.

If there is a workaround to ignore the cache I think that would solve my problem too.

I am using datasets version 2.8.0. 

### Steps to reproduce the bug

1. Start training run of GPU 0 loading dataset from
```
load_dataset(
    "json",
    data_files=tr_dataset_path,
    split=f"train",
    download_mode="force_redownload",
)
```
2. While GPU 0 is training, start an identical run on GPU 1. GPU 1 will produce the following error:

```

### Expected behavior

Expected behavior: 2nd GPU training run should run the same as 1st GPU training run.
