----------------------------------------

             Summary: Support to upload/read keys from encrypted buckets 
through S3G
                 Key: HDDS-5501
                 URL: https://issues.apache.org/jira/browse/HDDS-5501
             Project: Apache Ozone
          Issue Type: Improvement
            Reporter: Bharat Viswanadham
            Assignee: Bharat Viswanadham


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.
