Adds the option fs.s3a.requester.pays.enabled, which, if set to true, allows
the client to access S3 buckets where the requester is billed for the IO.

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)

Multi object delete of size more than 1000 is not supported by S3 and
fails with MalformedXML error. So implementing paging of requests to
reduce the number of keys in a single request. Page size can be configured

Adds a new map type WeakReferenceMap, which stores weak
references to values, and a WeakReferenceThreadMap subclass
to more closely resemble a thread local type, as it is a
map of threadId to value.
Construct it with a factory method and optional callback
for notification on loss and regeneration.
WeakReferenceThreadMap<WrappingAuditSpan> activeSpan =
new WeakReferenceThreadMap<>(
(k) -> getUnbondedSpan(),
this::noteSpanReferenceLost);
This is used in ActiveAuditManagerS3A for span tracking.

Part of HADOOP-17198. Support S3 Access Points.
HADOOP-18068. "upgrade AWS SDK to 1.12.132" broke the access point endpoint
translation.
Correct endpoints should start with "s3-accesspoint.", after SDK upgrade they start with
"s3.accesspoint-" which messes up tests + region detection by the SDK.

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.

See HADOOP-18091. S3A auditing leaks memory through ThreadLocal references
* Adds a new option fs.s3a.audit.enabled to controls whether or not auditing
is enabled. This is false by default.
* When false, the S3A auditing manager is NoopAuditManagerS3A,
which was formerly only used for unit tests and
during filsystem initialization.
* When true, ActiveAuditManagerS3A is used for managing auditing,
allowing auditing events to be reported.
* updates documentation and tests.
This patch does not fix the underlying leak. When auditing is enabled,
long-lived threads will retain references to the audit managers
of S3A filesystem instances which have already been closed.

Completely removes S3Guard support from the S3A codebase.
If the connector is configured to use any metastore other than
the null and local stores (i.e. DynamoDB is selected) the s3a client
will raise an exception and refuse to initialize.
This is to ensure that there is no mix of S3Guard enabled and disabled
deployments with the same configuration but different hadoop releases
-it must be turned off completely.
The "hadoop s3guard" command has been retained -but the supported
subcommands have been reduced to those which are not purely S3Guard
related: "bucket-info" and "uploads".
This is major change in terms of the number of files
changed; before cherry picking subsequent s3a patches into
older releases, this patch will probably need backporting
first.
Goodbye S3Guard, your work is done. Time to die.

With this update, the versions of key shaded dependencies are
jackson 2.12.3
httpclient 4.5.13
This backport patch does not include the TestArn changes needed
for the test to work with this version of the SDK; it is only
to be applied to branches without HADOOP-17198. "Support S3 Access Points".
If that patch is backported later, that test suite MUST be
updated to the latest version.

Cut modtime-based rename recovery as object modification time
is not updated during rename operation.
Applications will have to use etag API of HADOOP-17979
and implement it themselves.
Why not do the HEAD and etag recovery in ABFS client?
Cuts the IO capacity in half so kills job commit performance.
The manifest committer of MAPREDUCE-7341 will do this recovery
and act as the reference implementation of the algorithm.

Addresses transient failures in the following test classes:
* ITestAbfsStreamStatistics: Uses a filesystem level static instance to record read/write statistics, which also tracks these operations in other tests running in parallel. Marked for sequential-only run to avoid transient failure
* ITestAbfsRestOperationException: The use of a static member to track retry count causes transient failures when two tests of this class happen to run together. Switch to non-static variable for assertions on retry count

This switches the default behavior of S3A output streams
to warning that Syncable.hsync() or hflush() have been
called; it's not considered an error unless the defaults
are overridden.
This avoids breaking applications which call the APIs,
at the risk of people trying to use S3 as a safe store
of streamed data (HBase WALs, audit logs etc).

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.

This migrates the fs.s3a-server-side encryption configuration options
to a name which covers client-side encryption too.
fs.s3a.server-side-encryption-algorithm becomes fs.s3a.encryption.algorithm
fs.s3a.server-side-encryption.key becomes fs.s3a.encryption.key
The existing keys remain valid, simply deprecated and remapped
to the new values. If you want server-side encryption options
to be picked up regardless of hadoop versions, use
the old keys.
(the old key also works for CSE, though as no version of Hadoop
with CSE support has shipped without this remapping, it's less
relevant)

S3A S3Guard tests to skip if S3-CSE are enabled (#3263)
Follow on to
* HADOOP-13887. Encrypt S3A data client-side with AWS SDK (S3-CSE)
If the S3A bucket is set up to use S3-CSE encryption, all tests which turn
on S3Guard are skipped, so they don't raise any exceptions about
incompatible configurations.

This (big!) patch adds support for client side encryption in AWS S3,
with keys managed by AWS-KMS.
Read the documentation in encryption.md very, very carefully before
use and consider it unstable.
S3-CSE is enabled in the existing configuration option
"fs.s3a.server-side-encryption-algorithm":
fs.s3a.server-side-encryption-algorithm=CSE-KMS
fs.s3a.server-side-encryption.key=<KMS_KEY_ID>
You cannot enable CSE and SSE in the same client, although
you can still enable a default SSE option in the S3 console.
* Filesystem list/get status operations subtract 16 bytes from the length
of all files >= 16 bytes long to compensate for the padding which CSE
adds.
* The SDK always warns about the specific algorithm chosen being
deprecated. It is critical to use this algorithm for ranged
GET requests to work (i.e. random IO). Ignore.
* Unencrypted files CANNOT BE READ.
The entire bucket SHOULD be encrypted with S3-CSE.
* Uploading files may be a bit slower as blocks are now
written sequentially.
* The Multipart Upload API is disabled when S3-CSE is active.

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.
