ASF GitHub Bot commented on HADOOP-19654:
-----------------------------------------
steveloughran opened a new pull request, #8059:
URL: https://github.com/apache/hadoop/pull/8059
AWS SDK upgraded to 2.35.4.
This SDK has changed checksum/checksum headers handling significantly,
causing problems with third party stores, and, in some combinations AWS S3
itself.
The S3A connector has retained old behavior; options to change these
settings are now available.
The default settings are chosen for maximum compatiblity and performance.
fs.s3a.request.md5.header: true
fs.s3a.checksum.generation: false
fs.s3a.create.checksum.algorithm: ""
Consult the documentation for more details.

> Key: HADOOP-19654
> URL: https://issues.apache.org/jira/browse/HADOOP-19654
> Project: Hadoop Common
> Issue Type: Improvement
> Components: build, fs/s3
> Affects Versions: 3.5.0
> Reporter: Steve Loughran
> Assignee: Steve Loughran
> Priority: Major
> Labels: pull-request-available
>
> Upgrade to a recent version of 2.33.x or later while off the critical path of
> things.
> HADOOP-19485 froze the sdk at a version which worked with third party stores.
> Apparently the new version works; early tests show that Bulk Delete calls
> with third party stores complain about lack of md5 headers, so some tuning is
> clearly going to be needed.
