> URL: https://issues.apache.org/jira/browse/HDDS-5501
> Project: Apache Ozone
> Issue Type: New Feature
> Reporter: Bharat Viswanadham
> Assignee: Bharat Viswanadham
> Priority: Major
>
> When KMS is secured using hadoop.kms.authentication.type = KERBEROS. From S3 key put/get fails when decrypting the key due to missing Kerberos Credentials/KMS tokens.
> *Proposal to fix this:*
> 1. Introduce keytab for s3g
> 2. Make s3g acts as proxy for end users while decrypt kms key during put/get/mpu.
> The idea is similar to NFSgateway security model.
