[jira] [Created] (HADOOP-14130) Simplify DynamoDBClientFactory for creating Amazon DynamoDB clients

Mingliang Liu created HADOOP-14130:
--------------------------------------

             Summary: Simplify DynamoDBClientFactory for creating Amazon DynamoDB clients
                 Key: HADOOP-14130
                 URL: https://issues.apache.org/jira/browse/HADOOP-14130
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: fs/s3
            Reporter: Mingliang Liu
            Assignee: Mingliang Liu


So, we are using deprecated {{AmazonDynamoDBClient}} class to create a DynamoDB client instead of the recommended builder. We had discussion in [HADOOP-13345] for preferring region to endpoints for user to specify the DynamoDB region (if associated S3 region is unknown or different). We have reported inconsistent behavior if endpoint and S3 region are different in [HADOOP-14027]. We also noticed that {{DynamoDBMetadataStore}} may sometimes logs nonsense region. And in [HADOOP-13252], we also have feelings that file system URI is not needed to create a {{AWSCredentialProvider}}. Resultantly we don't need to pass down file system URI for creating a DynamoDB client.

So this JIRA is to change this, best effort.
