Includes HADOOP-18354. Upgrade reload4j to 1.22.2 due to XXE vulnerability (#4607).
Log4j 1.2.17 has been replaced by reloadj 1.22.2
SLF4J is at 1.7.36
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-19015. Increase fs.s3a.connection.maximum to 500 to minimize the risk of Timeout waiting for connection from the pool
Contributed By: Mukund Thakur
Move the org.apache.hadoop.{oncrpc, portmap} packages from the hadoop-nfs module
to the hadoop-common module.
This allows for use of the protocol beyond just NFS -including within HDFS itself.
Contributed by Xing Lin
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.

The enclosing root path is a common ancestor that should be used for temp and staging dirs
as well as within encryption zones and other restricted directories.

If fs.s3a.create.performance is set on a bucket
- All file overwrite checks are skipped, even if the caller says
otherwise.
- All directory existence checks are skipped.
- Marker deletion is *always* skipped.
This eliminates a HEAD and a LIST for every creation.
* New path capability "fs.s3a.create.performance.enabled" true
if the option is enabled.
* Parameterize ITestS3AContractCreate to expect the different
outcomes
* Parameterize ITestCreateFileCost similarly, with
changed cost assertions there.
* create(/) raises an IOE. existing bug only noticed here.

S3A directory delete and rename will optionally abort all pending multipart uploads
in their under their to-be-deleted paths when.
fs.s3a.directory.operations.purge.upload is true
It is off by default.
The filesystems hasPathCapability("fs.s3a.directory.operations.purge.upload")
probe will return true when this feature is enabled.
Multipart uploads may accrue from interrupted data writes, uncommitted
staging/magic committer jobs and other operations/applications. On AWS S3
lifecycle rules are the recommended way to clean these; this change improves
support for stores which lack these rules.
