   I am facing not the exact but a similar error using pyarrow version 10.0.0 
for a glue job.
   
   After calling `S3FileSystem` with an arn_role and using it to read a table, 
I get an access error
   
   `df = pq.read_table('key', columns = ["_id","preferences"], schema = 
custom_schema,filesystem=s3).to_pandas()`
   
   `OSError: When getting information for key 'X' in bucket 'X': AWS Error 
ACCESS_DENIED during HeadObject operation: No response body.`
   
   I thought it could be due to role policies but the role has enough 
permission on the S3 bucket and the trust-relationship looks fine.
   
   I have come with a workaround using `boto3.client()`, but I'd like to know 
what is causing the access denied.
