NIFI-2948 Fix DynamoDB Cached Credentials
----
> AWS DynamoDB Processors Do Not Update Credentials
> -------------------------------------------------
>
> Key: NIFI-2948
> URL: https://issues.apache.org/jira/browse/NIFI-2948
> Project: Apache NiFi
> Issue Type: Bug
> Affects Versions: 1.0.0, 0.7.0
> 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
