Summary: Extend S3A to WebIdentity
Key: HADOOP-18154
URL: https://issues.apache.org/jira/browse/HADOOP-18154
Project: Hadoop Common
Issue Type: Improvement
Components: fs/s3
Affects Versions: 2.10.1
Reporter: Ju Clarysse
We are using the latest version of
[delta-sharing|https://github.com/delta-io/delta-sharing] which takes advantage
of
[hadoop-aws|https://hadoop.apache.org/docs/current/hadoop-aws/tools/hadoop-aws/index.html]
(S3A) connector in [Hadoop release version
2.10.1|https://github.com/apache/hadoop/tree/rel/release-2.10.1] to mount an
AWS S3 File System. In our particular setup, all services are operated in
Amazon Elastic Kubernetes Service (EKS) and need to comply to the AWS security
concept [IAM roles for service
accounts|https://docs.aws.amazon.com/eks/latest/userguide/iam-roles-for-service-accounts.html]
(IRSA).
As [Delta sharing S3 connection|https://github.com/delta-io/delta-sharing#s3]
doesn't offer any corresponding support, we patched hadoop-aws-2.10.1 to
address this need via a new credentials provider class
org.apache.hadoop.fs.s3a.OIDCTokenCredentialsProvider. We also upgraded
dependency aws-java-sdk-bundle to its latest version 1.12.167 as [AWS
WebIdentityTokenCredentialsProvider
class|https://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/auth/WebIdentityTokenCredentialsProvider.html%E2%80%A6]
was not yet available in original version 1.11.271.
We believe that other delta-sharing users could benefit from this short-term
contribution. Sooner or later, delta-sharing owners will then have to upgrade
to a more recent version of hadoop-aws that is probably more widely used. The
effort to promote this change could be limited while the opportunity to make
other folks happy could be great.
