### Reproducible Example

```python
import modin.pandas as pd
import sqlalchemy as db
import ray

password = '...'
engine = db.create_engine(f'mysql://root:{password}@localhost:3306/test')

ray.init()

df = pd.DataFrame({
    'account-start': ['2017-02-03', '2017-03-03', '2017-01-01'],
    'client': ['Alice Anders', 'Bob Baker', 'Charlie Chaplin'],
    'balance': [-1432.32, 10.43, 30000.00],
    'db-id': [1234, 2424, 251],
    'proxy-id': [525, 1525, 2542],
    'rank': [52, 525, 32],
})

with engine.begin() as conn:
    df.to_sql('abc', conn, schema='test', if_exists='replace', index=False)
```


### Issue Description

The Ray worker nodes are unable to connect to the database as they are not getting the correct credentials.

### Expected Behavior

The contents of the DataFrame should be written to the table "abc."
