             Summary: Allow AWS processors to use DefaultAWSCredentialsProviderChain
                 Key: NIFI-3703
                 URL: https://issues.apache.org/jira/browse/NIFI-3703
             Project: Apache NiFi
          Issue Type: Improvement
          Components: Extensions
    Affects Versions: 1.1.1
            Reporter: Joseph Gresock
            Priority: Minor


Currently, the AWS processors assume that credentials must always be provided to the AWS SDK constructors.  When no credentials properties are specified, this causes AnonymousAWSCredentials to be used as a constructor argument to the AWS client.  While this may be intended in some cases, we should also allow for the option of not passing in any credentials, which causes the client to use DefaultAWSCredentialsProviderChain.getInstance(), behaving as specified here: http://docs.aws.amazon.com/sdk-for-java/v1/developer-guide/java-dg-roles.html
