The TimelineConnector.class has a hardcoded 1 minute connection time out, what makes the TestTimelineClient to a long running test (~15:30 min).
Decrease the timeout to 10ms will speed up the test run (~56 sec).
Adds a new option fs.s3a.s3express.create.session; default is true.
When false, this disables the CreateSession call to create/refresh temporary
session credentials when working with an Amazon S3 Express store.
This avoids having to give the caller the new IAM role permission,
at the expense of every remote call on the S3 Express store having to
include the latency of a checkup of IAM permissions.
* fs.s3a.s3express.create.session is set to false in tests which generate new
role permissions and call AssumeRole
* move ApiCallTimeoutException logic until after sdk exceptions get translated
to IOE. This lines up for any future AWS throwing up underlying cause here.
* Tests will automatically skip ACL, storage class, S3 Select or encryption tests
when target fs is S3Express.
* same for the out of order multipart uploader test cases, v1 listing.
* bucket tool s3 test treats invalid location error as a successful invocation
of the create bucket attempt

This adds borad support for Amazon S3 Express One Zone to the S3A connector,
particularly resilience of other parts of the codebase to LIST operations returning
paths under which only in-progress uploads are taking place.
hadoop-common and hadoop-mapreduce treewalking routines all cope with this;
distcp is left alone.
There are still some outstanding followup issues, and we expect more to surface
with extended use.
Contains HADOOP-18955. AWS SDK v2: add path capability probe "fs.s3a.capability.aws.v2
* lets us probe for AWS SDK version
* bucket-info reports it
Contains HADOOP-18961 S3A: add s3guard command "bucket"
hadoop s3guard bucket -create -region us-west-2 -zone usw2-az2 \
s3a://stevel--usw2-az2--x-s3/
* requires -zone if bucket is zonal
* rejects it if not
* rejects zonal bucket suffixes if endpoint is not aws (safety feature)
* imperfect, but a functional starting point.
New path capability "fs.s3a.capability.zonal.storage"
* Used in tests to determine whether pending uploads manifest paths
* cli tests can probe for this
* bucket-info reports it
* some tests disable/change assertions as appropriate
----
Shell commands fail on S3Express buckets if pending uploads.
New path capability in hadoop-common
"fs.capability.directory.listing.inconsistent"
1. S3AFS returns true on a S3 Express bucket
2. FileUtil.maybeIgnoreMissingDirectory(fs, path, fnfe)
decides whether to swallow the exception or not.
3. This is used in: Shell, FileInputFormat, LocatedFileStatusFetcher
Fixes with tests
* fs -ls -R
* fs -du
* fs -df
* fs -find
* S3AFS.getContentSummary() (maybe...should discuss)
* mapred LocatedFileStatusFetcher
* Globber, HADOOP-15478 already fixed that when dealing with
S3 inconsistencies
* FileInputFormat
S3Express CreateSession request is permitted outside audit spans.
S3 Bulk Delete calls request the store to return the list of deleted objects
if RequestFactoryImpl is set to trace.
log4j.logger.org.apache.hadoop.fs.s3a.impl.RequestFactoryImpl=TRACE
Test Changes
* ITestS3AMiscOperations removes all tests which require unencrypted
buckets. AWS S3 defaults to SSE-S3 everywhere.
* ITestBucketTool to test new tool without actually creating new
buckets.
* S3ATestUtils add methods to skip test suites/cases if store is/is not
S3Express
* Cutting down on "is this a S3Express bucket" logic to trailing --x-s3 string
and not worrying about AZ naming logic. commented out relevant tests.
* ITestTreewalkProblems validated against standard and S3Express stores
Outstanding
* Distcp: tests show it fails. Proposed: release notes.

x-amz-checksum header not found when signing S3Express messages
This modifies the custom signer in ITestCustomSigner to be a subclass
of AwsS3V4Signer with a goal of preventing signing problems with
S3 Express stores.
----
RemoteFileChanged renaming multipart file
Maps 412 status code to RemoteFileChangedException
Modifies huge file tests
-Adds a check on etag match for stat vs list
-ITestS3AHugeFilesByteBufferBlocks renames parent dirs, rather than
files, to replicate distcp better.
----
S3Express custom Signing cannot handle bulk delete
Copy custom signer into production JAR, so enable downstream testing
Extend ITestCustomSigner to cover more filesystem operations
- PUT
- POST
- COPY
- LIST
- Bulk delete through delete() and rename()
- list + abort multipart uploads
Suite is parameterized on bulk delete enabled/disabled.
To use the new signer for a full test run:
<property>
<name>fs.s3a.custom.signers</name>
<value>CustomSdkSigner:org.apache.hadoop.fs.s3a.auth.CustomSdkSigner</value>
</property>
<property>
<name>fs.s3a.s3.signing-algorithm</name>
<value>CustomSdkSigner</value>
</property>
Increases existing pool sizes, as with server scale and vector
IO, larger pools are needed
fs.s3a.connection.maximum 200
fs.s3a.threads.max 96
Adds new configuration options for v2 sdk internal timeouts,
both with default of 60s:
fs.s3a.connection.acquisition.timeout
fs.s3a.connection.idle.time
All the pool/timoeut options are covered in performance.md
Moves all timeout/duration options in the s3a FS to taking
temporal units (h, m, s, ms,...); retaining the previous default
unit (normally millisecond)
Adds a minimum duration for most of these, in order to recover from
deployments where a timeout has been set on the assumption the unit
was seconds, not millis.
Uses java.time.Duration throughout the codebase;
retaining the older numeric constants in
org.apache.hadoop.fs.s3a.Constants for backwards compatibility;
these are now deprecated.
Adds new class AWSApiCallTimeoutException to be raised on
sdk-related methods and also gateway timeouts. This is a subclass
of org.apache.hadoop.net.ConnectTimeoutException to support
existing retry logic.
+ reverted default value of fs.s3a.create.performance to false;
inadvertently set to true during testing.

With this upgrade, it is possible to connect to an Amazon S3 Express One Zone bucket.
Some tests from the S3A test suite will currently fail against a one zone bucket, as one zone buckets
do not support some S3 standard features (eg: SSE-KMS), and certain operations behave slightly
differently (eg: listMPU will return a directory that has incomplete MPUs).
