Description copied from interface: DynamoDBClientFactory

Create a DynamoDB client object from configuration. The DynamoDB client to create does not have to relate to any S3 buckets. All information needed to create a DynamoDB client is from the hadoop configuration. Specially, if the region is not configured, it will use the provided region parameter. If region is neither configured nor provided, it will indicate an error.

Specified by:

createDynamoDBClient in interface DynamoDBClientFactory

Parameters:

defaultRegion - the default region of the AmazonDynamoDB client

bucket - Optional bucket to use to look up per-bucket proxy secrets

credentials - credentials to use for authentication.

Returns:

a new DynamoDB client

Throws:

IOException - if any IO error happens
