[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.
