> Kinesalite bug fix (FLINK-9402) doesn't fully fix the problem.
> --------------------------------------------------------------
>
> Key: FLINK-10316
> URL: https://issues.apache.org/jira/browse/FLINK-10316
> Project: Flink
> Issue Type: Bug
> Components: Kinesis Connector
> Affects Versions: 1.5.0, 1.6.0, 1.7.0
> Reporter: Joseph Sims
> Priority: Minor
> Labels: pull-request-available
>
> Related to: https://issues.apache.org/jira/browse/FLINK-9402
> A fix (Flink-9402) was introduced to force the configurations to have
> *exactly* one of "aws.region" or "aws.endpoint", but the underlying problem
> wasn't entirely fixed.
> If "aws.endpoint" is set and "aws.region" is unset, a different exception is
> thrown, instead.
> In *KinesisConfigUtil.java*, *getValidatedProducerConfiguration()* calls:
> {code:java}
> validateAwsConfiguration(config)
> {code}
> Where the original fix was introduced ("aws.region" XOR "aws.endpoint")
> But a couple of lines later, *getValidatedProducerConfiguration()* then
> calls:
> {code:java}
> kpc.setRegion(config.getProperty(AWSConfigConstants.AWS_REGION));
> {code}
> Which explicitly checks for the existence of "aws.region", and throws an
> exception if it is not set.
> Thus, this class needs to be fixed such that "aws.region" is only required
> if "aws.endpoint" is unset, as the original ticket indicated.
> Also, *validateAwsConfiguration()* has a minor bug where is labels the
> "aws.endpoint" incorrectly.
> Current:
> {code:java}
> if (!(config.containsKey(AWSConfigConstants.AWS_REGION) ^
> config.containsKey(ConsumerConfigConstants.AWS_ENDPOINT))) {
> // per validation in AwsClientBuilder
> throw new IllegalArgumentException(String.format("Either AWS region ('%s')
> or AWS endpoint ('%s') must be set in the config.",
> AWSConfigConstants.AWS_REGION, AWSConfigConstants.AWS_REGION));
> }
> {code}
> But should be:
> {code:java}
> if (!(config.containsKey(AWSConfigConstants.AWS_REGION) ^
> config.containsKey(ConsumerConfigConstants.AWS_ENDPOINT))) {
> // per validation in AwsClientBuilder
> throw new IllegalArgumentException(String.format("Either AWS region ('%s')
> or AWS endpoint ('%s') must be set in the config.",
> AWSConfigConstants.AWS_REGION, ConsumerConfigConstants.AWS_ENDPOINT));
> }
> {code}
