Pandas version checks
-
I have checked that this issue has not already been reported.
-
I have confirmed this bug exists on the latest version of pandas.
-
I have confirmed this bug exists on the main branch of pandas.
Reproducible Example
import os
import pandas as pd
os.environ["AWS_DEFAULT_REGION"] = "us-west-2"
os.environ["AWS_CONFIG_FILE"] = "invalid"
os.environ["AWS_SHARED_CREDENTIALS_FILE"] = "invalid"
os.environ["AWS_ACCESS_KEY_ID"] = "invalid"
os.environ["AWS_SECRET_ACCESS_KEY"] = "invalid"
# displays without error
display(pd.read_csv("s3://modin-datasets/testing/multiple_csv/test_data0.csv"))
# OSError from AWS error ACCESS_DENIED
display(pd.read_parquet("s3://modin-datasets/testing/test_data.parquet"))
del os.environ["AWS_ACCESS_KEY_ID"]
del os.environ["AWS_SECRET_ACCESS_KEY"]
# displays without error
display(pd.read_csv("s3://modin-datasets/testing/multiple_csv/test_data0.csv"))
# displays without error
display(pd.read_parquet("s3://modin-datasets/testing/test_data.parquet"))
Issue Description
I'm trying to use pandas to read a public CSV file and a public parquet file from an s3 bucket. When I have the environment variables AWS_ACCESS_KEY_ID
and AWS_ACCESS_KEY_ID
set to anything (my valid credentials or some invalid credentials), reading the CSV works, but reading the parquet file gives an error from an AWS "ACCESS_DENIED" error.
When I remove AWS_ACCESS_KEY_ID
and AWS_ACCESS_KEY_ID
, I can read with both CSV and parquet.
Note that in the example above I have set the correct AWS_DEFAULT_REGION
and I have also set AWS_CONFIG_FILE
and AWS_SHARED_CREDENTIALS_FILE
to a nonexistent location to illustrate that whether I have credentials in ~/.aws
doesn't matter.
Expected Behavior
I should be able to read both the CSV file and the parquet file from s3, whether or not I have any kind of credentials in my environment. Both the files are open to the public. I think pandas is supposed to use the retry mechanism here for this.
