>             Project: Apache NiFi
>          Issue Type: Bug
>    Affects Versions: 0.7.0, 1.0.0
>            Reporter: James Wing
>            Priority: Minor

> Following a report to the dev email list, there appears to be a bug in the AWS DynamoDB processors where the AWS credentials are cached by the processor once started, and not updated even if the processor is stopped, reconfigured, and started.
> The problem appears to be [AbstractDynamoDBProcessor::getDynamoDB|https://github.com/apache/nifi/blob/rel/nifi-1.0.0/nifi-nar-bundles/nifi-aws-bundle/nifi-aws-processors/src/main/java/org/apache/nifi/processors/aws/dynamodb/AbstractDynamoDBProcessor.java#L218], which assigns the dynamo client object to a class variable only once.
> *Repro Steps*
> # Add GetDynamoDB processor
> # Configure GetDynamoDB required properties but *not* any credential fields
> # Start the processor
> # Run a flowfile through - it should fail with "MissingAuthenticationTokenException" error
> # Stop the GetDynamoDB processor
> # Configure valid AWS credentials
> # Start the processor
> # Run a flowfile through - it should fail again with "MissingAuthenticationTokenException" still using the old credentials
