Mingliang Liu commented on HADOOP-13650:
----------------------------------------
{{S3AFileSystem#initialize(name, conf)}}, name may have the user:pass login
info for creating the credentials of AWS client. Also the S3AFS is used to get
the bucket name and region. This may bring extra work if we only support
initializing {{DDBMetadataStore}} via Configuration parameter only. Let's
figure out this later; by now let's rely on the S3AFS to initialize the
DDBMetadataStore.
> S3Guard: Provide command line tools to manipulate metadata store.

> Similar systems like EMRFS has the CLI tools to manipulate the metadata
> store, i.e., create or delete metadata store, or {{import}}, {{sync}} the
> file metadata between metadata store and S3.
> http://docs.aws.amazon.com//ElasticMapReduce/latest/ReleaseGuide/emrfs-cli-reference.html
> S3Guard should offer similar functionality.
