load_dataset error
Hi, @lion-ops.

In our Continuous Integration we have many tests on loading JSON files and all of them work properly.

Could you please share your "train.json" file, so that we can try to reproduce the issue you have?  > Hi, @lion-ops.

Thank you for your reply. I can load it normally in another server. Is it possible that the disk of my server is a network disk in the LAN, so it will be downloaded from the LAN and get stuck?
### Describe the bug

Why does the program get stuck when I use load_dataset method, and it still gets stuck after loading for several hours? In fact, my json file is only 21m, and I can load it in one go using open('', 'r').

### Steps to reproduce the bug

1. pip install datasets==2.19.2
2. from datasets import Dataset, DatasetDict, NamedSplit, Split, load_dataset
3. data = load_dataset('json', data_files='train.json')

### Expected behavior

It is able to load my json correctly

### Environment info

datasets==2.19.2
