HADOOP-19043. S3A: Regression: ITestS3AOpenCost fails on prefetch test runs (#6465)
Disables the new tests added in:

HADOOP-19027. S3A: S3AInputStream doesn't recover from HTTP/channel exceptions #6425

The underlying issue here is that the block prefetch code can identify
when there's a mismatch between declared and actual length, and doesn't
store any of the incomplete buffer.

This should be addressed in HADOOP-18184.

HADOOP-19057. S3A: Landsat bucket used in tests no longer accessible (#6515)
The AWS landsat data previously used in some S3A tests is no
longer accessible

This PR moves to the new external file
s3a://noaa-cors-pds/raw/2024/001/akse/AKSE001x.24_.gz

* Large enough file for scale tests
* Bucket supports anonymous access
* Ends in .gz to keep codec tests happy
* No spaces in path to keep bucket-info happy

Test Code Changes
* Leaves the test key name alone: fs.s3a.scale.test.csvfile
* Rename all methods and fields move remove "csv" from their names and
  move to "external file" we no longer require it to be CSV.
* Path definition and helper methods have been moved to PublicDatasetTestUtils
* Improve error reporting in ITestS3AInputStreamPerformance if the file
  is too short
  
With S3 Select removed, there is no need for the file to be
a CSV file; there is a test which tries to unzip it; other
tests have a minimum file size.

Consult the JIRA for the settings to add to auth-keys.xml
to switch earlier builds to this same file.

HADOOP-19045. CreateSession Timeout - followup (#6532)
This is a followup to PR:
HADOOP-19045. S3A: Validate CreateSession Timeout Propagation (#6470)

Remove all declarations of fs.s3a.connection.request.timeout
in
- hadoop-common/src/main/resources/core-default.xml
- hadoop-aws/src/test/resources/core-site.xml

New test in TestAwsClientConfig to verify that the value
defined in fs.s3a.Constants class is used.

This is brittle to someone overriding it in their test setups,
but as this test is intended to verify that the option is not
explicitly set, there's no workaround.

HADOOP-18883. [ABFS]: Expect-100 JDK bug resolution: prevent multiple server calls (#6022)
Address JDK bug JDK-8314978 related to handling of HTTP 100
responses. 

https://bugs.openjdk.org/browse/JDK-8314978

In the AbfsHttpOperation, after sendRequest() we call processResponse()
method from AbfsRestOperation.
Even if the conn.getOutputStream() fails due to expect-100 error, 
we consume the exception and let the code go ahead.
This may call getHeaderField() / getHeaderFields() / getHeaderFieldLong() after
getOutputStream() has failed. These invocation all lead to server calls.

This commit aims to prevent this.
If connection.getOutputStream() fails due to an Expect-100 error,
the ABFS client does not invoke getHeaderField(), getHeaderFields(),
getHeaderFieldLong() or getInputStream().

getResponseCode() is safe as on the failure it sets the
responseCode variable in HttpUrlConnection object.

HADOOP-19027. S3A: S3AInputStream doesn't recover from HTTP/channel exceptions (#6425)
Differentiate from "EOF out of range/end of GET" from
"EOF channel problems" through
two different subclasses of EOFException and input streams to always
retry on http channel errors; out of range GET requests are not retried.
Currently an EOFException is always treated as a fail-fast call in read()

This allows for all existing external code catching EOFException to handle
both, but S3AInputStream to cleanly differentiate range errors (map to -1)
from channel errors (retry)

- HttpChannelEOFException is subclass of EOFException, so all code
  which catches EOFException is still happy.
  retry policy: connectivityFailure
- RangeNotSatisfiableEOFException is the subclass of EOFException
  raised on 416 GET range errors.
  retry policy: fail
- Method ErrorTranslation.maybeExtractChannelException() to create this
  from shaded/unshaded NoHttpResponseException, using string match to
  avoid classpath problems.
- And do this for SdkClientExceptions with OpenSSL error code WFOPENSSL0035.
  We believe this is the OpenSSL equivalent.
- ErrorTranslation.maybeExtractIOException() to perform this translation as
  appropriate.

S3AInputStream.reopen() code retries on EOF, except on
 RangeNotSatisfiableEOFException,
 which is converted to a -1 response to the caller
 as is done historically.

S3AInputStream knows to handle these with
 read(): HttpChannelEOFException: stream aborting close then retry
 lazySeek(): Map RangeNotSatisfiableEOFException to -1, but do not map
  any other EOFException class raised.

This means that
* out of range reads map to -1
* channel problems in reopen are retried
* channel problems in read() abort the failed http connection so it
  isn't recycled

Tests for this using/abusing mocking.

Testing through actually raising 416 exceptions and verifying that
readFully(), char read() and vector reads are all good.

There is no attempt to recover within a readFully(); there's
a boolean constant switch to turn this on, but if anyone does
it a test will spin forever as the inner PositionedReadable.read(position, buffer, len)
downgrades all EOF exceptions to -1.
A new method would need to be added which controls whether to downgrade/rethrow
exceptions.

What does that mean? Possibly reduced resilience to non-retried failures
on the inner stream, even though more channel exceptions are retried on.

HADOOP-18997. S3A: Add option fs.s3a.s3express.create.session to disable S3Express CreateSession (#6316)
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

HADOOP-18996. S3A to provide full support for S3 Express One Zone (#6308)
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.

HADOOP-18915. Tune/extend S3A http connection and thread pool settings (#6180)
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.

HADOOP-18908. Improve S3A region handling. (#6187)
S3A region logic improved for better inference and
to be compatible with previous releases

1. If you are using an AWS S3 AccessPoint, its region is determined
   from the ARN itself.
2. If fs.s3a.endpoint.region is set and non-empty, it is used.
3. If fs.s3a.endpoint is an s3.*.amazonaws.com url, 
   the region is determined by by parsing the URL 
   Note: vpce endpoints are not handled by this.
4. If fs.s3a.endpoint.region==null, and none could be determined
   from the endpoint, use us-east-2 as default.
5. If fs.s3a.endpoint.region=="" then it is handed off to
   The default AWS SDK resolution process.

Consult the AWS SDK documentation for the details on its resolution
process, knowing that it is complicated and may use environment variables,
entries in ~/.aws/config, IAM instance information within
EC2 deployments and possibly even JSON resources on the classpath.
Put differently: it is somewhat brittle across deployments.

HADOOP-18889. S3A v2 SDK third party support (#6141)
Tune AWS v2 SDK changes based on testing with third party stores
including GCS. 

Contains HADOOP-18889. S3A v2 SDK error translations and troubleshooting docs

* Changes needed to work with multiple third party stores
* New third_party_stores document on how to bind to and test
  third party stores, including google gcs (which works!)
* Troubleshooting docs mostly updated for v2 SDK

Exception translation/resilience

* New AWSUnsupportedFeatureException for unsupported/unavailable errors
* Handle 501 method unimplemented as one of these
* Error codes > 500 mapped to the AWSStatus500Exception if no explicit
  handler.
* Precondition errors handled a bit better
* GCS throttle exception also recognized.
* GCS raises 404 on a delete of a file which doesn't exist: swallow it.
* Error translation uses reflection to create IOE of the right type.
  All IOEs at the bottom of an AWS stack chain are regenerated.
  then a new exception of that specific type is created, with the top level ex
  its cause. This is done to retain the whole stack chain.
* Reduce the number of retries within the AWS SDK
* And those of s3a code.
* S3ARetryPolicy explicitly declare SocketException as connectivity failure
  but subclasses BindException
* SocketTimeoutException also considered connectivity  
* Log at debug whenever retry policies looked up
* Reorder exceptions to alphabetical order, with commentary
* Review use of the Invoke.retry() method 

 The reduction in retries is because its clear when you try to create a bucket
 which doesn't resolve that the time for even an UnknownHostException to
 eventually fail over 90s, which then hit the s3a retry code.
 - Reducing the SDK retries means these escalate to our code better.
 - Cutting back on our own retries makes it a bit more responsive for most real
 deployments.
 - maybeTranslateNetworkException() and s3a retry policy means that
   unknown host exception is recognised and fails fast.
