-----------------------------------------------------------------
For v0 patch, I tested against us-west-2 using {{cmvn -Dit.test='ITestS3A*'
-Dtest=none -Dscale -Ds3guard -Ddynamo -q clean verify}}. Will test again as
there might be changes per review. {{S3GuardTool}} is definitely broken with
this change, but the fix should not be complex. I'll work on that with incoming
v1 patch (_UPDATE: uploaded the v1 patch_).

> 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.
