Prasanth Jayachandran commented on HDDS-3765:
---------------------------------------------

when testing fluentd s3 plugin with o3. It failed if the object key either had 
a leading slash and even double slashes anywhere in the key. There was a case 
where variable substitution returned empty resulting in double slash in the 
object key. That also cause 500 error and fluentd was stuck forever as it 
cannot upload the chunk and gateway went down.

> Fluentd writing to secure Ozone S3 API fails with 500 Error.
