----------------------------------------
Hi, [~fabbri], [~liuml07], [[email protected]]. Happy new year.
[~liuml07], regarding HADOOP-13650 (CLI), for
{{DynamoDBMetadataStore#initialize(Configuration)}}, does it still require s3
fs name defined in the configuration? I think that the user might not be used
to specify {{fs.defaultFS}} to an S3 bucket. It seems that logic that creating
AWS credential from S3 URL is deeply in the code. The consequence of it is
that even {{hadoop s3a [init|destroy]}} can directly use a DynamoDB URL to
create or clear / destroy the metadata store, it still requires the user to
specify a s3a url {{s3a://bucket}} to create the FS instance. It is also
undesirable for mutli-bucket cases, i.e., sharing one dynamodb table with
multiple buckets.
Should we get the current form of CLI committed first, then we change the CLI
parameters after the feature branch merged into trunk?
Thanks

> This issue proposes S3Guard, a new feature of S3A, to provide an option for a
> stronger consistency model than what is currently offered. The solution
> coordinates with a strongly consistent external store to resolve
> inconsistencies caused by the S3 eventual consistency model.
