             Summary: S3Guard: fix multi-bucket integration tests
                 Key: HADOOP-14013
                 URL: https://issues.apache.org/jira/browse/HADOOP-14013
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: fs/s3
    Affects Versions: HADOOP-13345
            Reporter: Aaron Fabbri
            Assignee: Aaron Fabbri


HADOOP-13449 adds support for DynamoDBMetadataStore.

The code currently supports two options for choosing DynamoDB table names:
1. Use name of each s3 bucket and auto-create a DynamoDB table for each.
2. Configure a table name in the {{fs.s3a.s3guard.ddb.table}} parameter.

One of the issues is with accessing read-only buckets.  If a user accesses a read-only bucket with credentials that do not have DynamoDB write permissions, they will get errors when trying to access the read-only bucket.  This manifests causes test failures for {{ITestS3AAWSCredentialsProvider}}.

Goals for this JIRA:
- Fix {{ITestS3AAWSCredentialsProvider}} in a way that makes sense for the real use-case.
- Allow for a "one DynamoDB table per cluster" configuration with a way to chose which credentials are used for DynamoDB.
- Document limitations etc. in the s3guard.md site doc.
