> Key: HADOOP-14345
> URL: https://issues.apache.org/jira/browse/HADOOP-14345
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Reporter: Mingliang Liu
> Assignee: Steve Loughran
> Priority: Minor
>
> I don't know if this is considered a requested feature from S3Guard code, as
> the user can always provision the DDB tables via the cloud portal.
> Implementing should be straightforward. The {{DynamoDBMetadataStore}} has
> provision method to use.
