Christoph Pirkl commented on SPARK-10969:
-----------------------------------------

This issue is about adding additional (optional) credentials for dynamodb and 
cloudwatch. In my opinion it would be better to introduce a parameter object 
containing all credentials than to have four additional String parameters.

I don't think it is possible to use the same mechanism as in 
https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/deploy/SparkHadoopUtil.scala#L98
 (i.e. reading the credentials from System.getenv()) as this would mean 
defining environment variables on each node.

A generic configuration using a map would mean a potential error source when 
you mistype a parameter name.

> Spark Streaming Kinesis: Allow specifying separate credentials for Kinesis

>             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()}}.
