I only quickly skimmed the Hadoop docs and found this (although it is
not documented very well I might add). If this does not do the trick,
I'd suggest to reach out to the Hadoop project, since we're using their
S3 filesystem.

Hey Chesnay,
Thank you for getting back with that! I tried setting that too, it
still gives me the same exception. Is there something else that I'm
missing?
I also have
fs.s3a.bucket.<bucket-name>.server-side-encryption-algorithm=SSE-KMS
and fs.s3a.bucket.<bucket-name>.server-side-encryption.key set.
Is there no need to set the md5 hash value manually while sinking? The
fs.s3a.etag.checksum.enabled: true will do it for me? And Do I need to
specify anywhere that we have to use md5 hashing?

Hello team,
I’m developing a system where we are trying to sink to an immutable s3
bucket. This bucket has server side encryption set as KMS. The DataStream
sink works perfectly fine when I don’t use the immutable bucket but when I
use an immutable bucket, I get exceptions regarding multipart upload
failures. It says we need to enable md5 hashing for the put object to work.
Here’s the stack trace:

My questions are:
1. Is this md5 hashing a mandatory rule to support this? The first part of
the file always gets uploaded to s3 but next part onward, it fails.
According to was s3 documentation for immutable buckets (with object locks)
they say it’s mandatory -
https://docs.aws.amazon.com/AmazonS3/latest/API/API_PutObject.html
“The Content-MD5 header is required for any request to upload an object
with a retention period configured using Amazon S3 Object Lock. For more
information about Amazon S3 Object Lock, see Amazon S3 Object Lock Overview
<https://docs.aws.amazon.com/AmazonS3/latest/dev/object-lock-overview.html>
<https://docs.aws.amazon.com/AmazonS3/latest/dev/object-lock-overview.html> in
the *Amazon Simple Storage Service Developer Guide*."
2. If it’s mandatory, how do I set this HTTP header while sinking? I
checked most of the documentation and tried going through the source code
too but couldn’t really find a provision where we could set the headers for
a request that goes in as a sink.
