Generated URI not working with pandas

[n-raghu]

Hi,
I have a private S3 bucket and created an URI using this tool as below:
./sign_s3_url.bash --bucket 'eae-data-test' --aws-access-key-id 'my-key' --aws-secret-access-key 'secret-key' --file-path 'hdf/customer' --region 'us-east-1' --minute-expire 10001

Above script created a link similar as below:
https://s3.amazonaws.com/eae-data-test/hdf/customer?AWSAccessKeyId=AK6&Expires=1533802548&Signature=MJ%2E%3D

I tried using this link in pandas as below:
import pandas as pd
df=pd.read_sql('SELECT * FROM SQL-SERVER-TABLE', sql-server-pypyodbc-connection)
uri='https://s3.amazonaws.com/eae-data-test/hdf/customer?AWSAccessKeyId=AK6&Expires=1533802548&Signature=MJ%2E%3D'
df.to_hdf(uri,key='df')

Above 'to_hdf' throws below error:
File "/eae/env/dts/lib/python3.6/site-packages/pandas/core/generic.py", line 1471, in to_hdf
return pytables.to_hdf(path_or_buf, key, self, **kwargs)

OSError: https://s3.amazonaws.com/eae-data-test/hdf does not exist

Could you please help me with this?
