HADOOP-18382. AWS SDK v2 upgrade prerequisites (#4698)
This patch prepares the hadoop-aws module for a future migration to using the v2 AWS SDK (HADOOP-18073) That upgrade will be incompatible; this patch prepares for it: -marks some credential providers and other classes and methods as @deprecated. -updates site documentation -reduces the visibility of the s3 client; other than for testing, it is kept private to the S3AFileSystem class. -logs some warnings when deprecated APIs are used. The warning messages are printed only once per JVM's life. To disable them, set the log level of org.apache.hadoop.fs.s3a.SDKV2Upgrade to ERROR Contributed by Ahmar Suhail

# Upgrading S3A to AWS SDK V2
|
||||
|
||||
This document explains the upcoming work for upgrading S3A to AWS SDK V2.
|
||||
This work is tracked in [HADOOP-18073](https://issues.apache.org/jira/browse/HADOOP-18073).
|
||||
|
||||
## Why the upgrade?
|
||||
|
||||
- Moving to SDK V2 will provide performance benefits.
|
||||
For example, the [transfer manager for SDKV2](https://aws.amazon.com/blogs/developer/introducing-amazon-s3-transfer-manager-in-the-aws-sdk-for-java-2-x/)
|
||||
is built using java bindings of the AWS Common Runtime S3
|
||||
client (https://github.com/awslabs/aws-crt-java) (CRT).
|
||||
CRT is a set of packages written in C, designed for maximising performance when interacting with AWS
|
||||
services such as S3.
|
||||
- New features such as [additional checksum algorithms](https://aws.amazon.com/blogs/aws/new-additional-checksum-algorithms-for-amazon-s3/)
|
||||
which S3A will benefit from are not available in SDKV1.
|
||||
|
||||
## What's changing?
|
||||
|
||||
The [SDK V2](https://github.com/aws/aws-sdk-java-v2) for S3 is very different from
|
||||
[SDK V1](https://github.com/aws/aws-sdk-java), and brings breaking changes for S3A.
|
||||
A complete list of the changes can be found in the [Changelog](https://github.com/aws/aws-sdk-java-v2/blob/master/docs/LaunchChangelog.md#41-s3-changes).
|
||||
|
||||
The major changes and how this affects S3A are listed below.
|
||||
|
||||
### Package Change
|
||||
|
||||
Package names have changed, all classes in SDK V2 are under `software.amazon.awssdk`, SDK V1 classes
|
||||
were under `com.amazonaws`.
|
||||
|
||||
### Credential Providers
|
||||
|
||||
- Interface change: [com.amazonaws.auth.AWSCredentialsProvider](https://github.com/aws/aws-sdk-java/blob/master/aws-java-sdk-core/src/main/java/com/amazonaws/auth/AWSCredentialsProvider.java)
|
||||
has been replaced by [software.amazon.awssdk.auth.credentials.AwsCredentialsProvider](https://github.com/aws/aws-sdk-java-v2/blob/master/core/auth/src/main/java/software/amazon/awssdk/auth/credentials/AwsCredentialsProvider.java).
|
||||
- Credential provider class changes: the package and class names of credential providers have
|
||||
changed.
|
||||
|
||||
The change in interface will mean that custom credential providers will need to be updated to now
|
||||
implement `AwsCredentialsProvider` instead of `AWSCredentialProvider`.
|
||||
|
||||
Due to change in class names, references to SDK V1 credential providers
|
||||
in `fs.s3a.aws.credentials.provider` will need to be updated to reference V2 providers.
|
||||
|
||||
### Delegation Tokens
|
||||
|
||||
Custom credential providers used in delegation token binding classes will also need to be updated.
|
||||
|
||||
### AmazonS3 replaced by S3Client
|
||||
|
||||
The s3 client is an instance of `S3Client` in V2 rather than `AmazonS3`.
|
||||
|
||||
For this reason, the `S3ClientFactory` will be deprecated and replaced by one that creates a V2
|
||||
`S3Client`.
|
||||
|
||||
The `getAmazonS3ClientForTesting()` method will also be updated to return the `S3Client`.
|
||||
|
||||
### Signers
|
||||
|
||||
Interface change: [com.amazonaws.auth.Signer](https://github.com/aws/aws-sdk-java/blob/master/aws-java-sdk-core/src/main/java/com/amazonaws/auth/Signer.java)
|
||||
has been replaced by [software.amazon.awssdk.core.signer.Signer](https://github.com/aws/aws-sdk-java-v2/blob/master/core/sdk-core/src/main/java/software/amazon/awssdk/core/signer/Signer.java).
|
||||
|
||||
The change in signers will mean the custom signers will need to be updated to implement the new
|
||||
interface.

The client supports multiple authentication mechanisms and can be configured as to

|

|

S3A will soon be upgraded to [AWS's Java SDK V2](https://github.com/aws/aws-sdk-java-v2).
|
||||
For more information on the upgrade and what's changing, see
|
||||
[Upcoming upgrade to AWS Java SDK V2](./aws_sdk_upgrade.html).
|
||||
|
||||
S3A logs the following warnings for things that will be changing in the upgrade. To disable these
|
||||
logs, comment out `log4j.logger.org.apache.hadoop.fs.s3a.SDKV2Upgrade` in log4j.properties.
|
||||
|
||||
### <a name="ProviderReferenced"></a> `Directly referencing AWS SDK V1 credential provider`
|
||||
|
||||
This will be logged when an AWS credential provider is referenced directly in
|
||||
`fs.s3a.aws.credentials.provider`.
|
||||
For example, `com.amazonaws.auth.AWSSessionCredentialsProvider`
|
||||
|
||||
To stop this warning, remove any AWS credential providers from `fs.s3a.aws.credentials.provider`.
|
||||
Instead, use S3A's credential providers.
|
||||
|
||||
### <a name="ClientRequested"></a> `getAmazonS3ClientForTesting() will be removed`
|
||||
|
||||
This will be logged when `getAmazonS3ClientForTesting()` is called to get the S3 Client. With V2,
|
||||
the S3 client will change from type `com.amazonaws.services.s3.AmazonS3` to
|
||||
`software.amazon.awssdk.services.s3.S3Client`, and so this method will be removed.
|
||||
|
||||
### <a name="DelegationTokenProvider"></a>
|
||||
### `Custom credential providers used in delegation tokens binding classes will need to be updated`
|
||||
|
||||
This will be logged when delegation tokens are used.
|
||||
Delegation tokens allow the use of custom binding classes which can implement custom credential
|
||||
providers.
|
||||
These credential providers will currently be implementing
|
||||
`com.amazonaws.auth.AWSCredentialsProvider` and will need to be updated to implement
|
||||
`software.amazon.awssdk.auth.credentials.AwsCredentialsProvider`.
|
||||
|
||||
### <a name="CustomSignerUsed"></a>
|
||||
### `The signer interface has changed in AWS SDK V2, custom signers will need to be updated`
|
||||
|
||||
This will be logged when a custom signer is used.
|
||||
Custom signers will currently be implementing `com.amazonaws.auth.Signer` and will need to be
|
||||
updated to implement `software.amazon.awssdk.core.signer.Signer`.
|
||||
|
||||
### <a name="GetObjectMetadataCalled"></a>
|
||||
### `getObjectMetadata() called. This operation and it's response will be changed`
|
||||
|
||||
This will be logged when `getObjectMetadata` is called. In SDK V2, this operation has changed to
|
||||
`headObject()` and will return a response of the type `HeadObjectResponse`.
