The ordering of the resolution of new and deprecated s3a encryption options & secrets is the same when JCEKS and other hadoop credentials stores are used to store them as
when they are in XML files: per-bucket settings always take priority over global values,
even when the bucket-level options use the old option names.

The option fs.s3a.object.content.encoding declares the content encoding to be set on files when they are written; this is served up in the "Content-Encoding" HTTP header when reading objects back in.
This is useful for people loading the data into other tools in the AWS ecosystem which don't use file extensions to infer compression type (e.g. serving compressed files from S3 or importing into RDS)

Add support for S3 Access Points. This provides extra security as it
ensures applications are not working with buckets belong to third parties.
To bind a bucket to an access point, set the access point (ap) ARN,
which must be done for each specific bucket, using the pattern
fs.s3a.bucket.$BUCKET.accesspoint.arn = ARN
* The global/bucket option `fs.s3a.accesspoint.required` to
mandate that buckets must declare their access point.
* This is not compatible with S3Guard.
Consult the documentation for further details.

Addresses the problem of processes running out of memory when
there are many ABFS output streams queuing data to upload,
especially when the network upload bandwidth is less than the rate
data is generated.
ABFS Output streams now buffer their blocks of data to
"disk", "bytebuffer" or "array", as set in
"fs.azure.data.blocks.buffer"
When buffering via disk, the location for temporary storage
is set in "fs.azure.buffer.dir"
For safe scaling: use "disk" (default); for performance, when
confident that upload bandwidth will never be a bottleneck,
experiment with the memory options.
The number of blocks a single stream can have queued for uploading
is set in "fs.azure.block.upload.active.blocks".
The default value is 20.

* HDFS-16129. Fixing the signature secret file misusage in HttpFS.
The signature secret file was not used in HttpFs.
- if the configuration did not contain the deprecated
httpfs.authentication.signature.secret.file option then it
used the random secret provider
- if both option (httpfs. and hadoop.http.) was set then
the HttpFSAuthenticationFilter could not read the file
because the file path was not substituted properly
!NOTE! behavioral change: the deprecated httpfs. configuration
values are overwritten with the hadoop.http. values.
The commit also contains a follow up change to the YARN-10814,
empty secret files will result in a random secret provider.
