             Summary: Spark Streaming Kinesis: Allow specifying separate credentials for Kinesis and DynamoDB
                 Key: SPARK-10969
                 URL: https://issues.apache.org/jira/browse/SPARK-10969
             Project: Spark
          Issue Type: Improvement
          Components: Streaming
    Affects Versions: 1.5.1
            Reporter: Christoph Pirkl
            Priority: Critical


{{KinesisUtils.createStream()}} allows specifying only one set of AWS credentials that will be used by Amazon KCL for accessing Kinesis, DynamoDB and CloudWatch.

h5. Motivation
In a scenario where one needs to read from a Kinesis Stream owned by a different AWS account the user usually has minimal rights (i.e. only read from the stream). In this case creating the DynamoDB table in KCL will fail.

h5. Proposal
My proposed solution would be to allow specifying multiple credentials in {{KinesisUtils.createStream()}} for Kinesis, DynamoDB and CloudWatch. The additional credentials could then be passed to the constructor of {{KinesisClientLibConfiguration}} or method {{KinesisClientLibConfiguration.withDynamoDBClientConfig()}}.
