load_dataset() cannot find dataset_info.json with multiple training runs in parallel
Author: mtoles | Pull request: no | State: closed

### 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.
