Github user jvwing commented on the issue: https://github.com/apache/nifi/pull/2291 @baank, thanks for the latest update. Good news, we're getting down to the nit-picks: 1. I had a checkstyle error running the full build with contrib check on nifi-aws-service-api `UnusedImports: Unused import - com.amazonaws.services.s3.AmazonS3Encryption`. 2. In your services, some of the Property Descriptors are marked as supporting expression language, but EL is not evaluated when extracting the value of the property (like `context.getProperty(KMS_CMK_ID).evaluateAttributeExpressions().getValue()` or similar). We should either evaluate the expressions or not mark them as supporting expression language: * EncryptedS3ClientService (KMS_CMK_ID, SECRET_KEY, PRIVATE_KEY, PUBLIC_KEY) * EncryptedS3PutEnrichmentService (KMS_KEY_ID, CUSTOMER_KEY) It's fine to update this PR. I'll work out rebasing and squashing when we're ready.
