Steve Loughran commented on HADOOP-13899:
-----------------------------------------


# {{DynamoDBMetadataStore}] to use {{translateException()}} for failures in in {{init}}.
# {{DynamoDBMetadataStore}] uses authority to get bucket {{s3afs.getUri().getAuthority()}} when it must be getHost(). Fix: Switch to {{S3AFilesystem.getBucket()}}.
# move the public S3Guard constants into S3A.Constants for use by other applications.
# Define constants for the standard implementations of the metastore (null, local, dynamo)
# on a failure to init an implementation, fail, rather than fallback to Null. If there is a problem, it must be considered fatal. Otherwise, if dynamoDB is
being authoritative, a client may think it is using, but as it isn't: corruption
# Document this stuff a bit

> While setting up clients for testing dynamo DB, make the tweaks to the dynamo store and the s3guard code for better use downstream. These are the kind of things we need to round off the code for production use.
