Chris Nauroth commented on HADOOP-13650:
----------------------------------------

Actually, part of my last comment was wrong.  Even though it would be a 
built-in, the hadoop-aws jars would only go onto the classpath when the user is 
invoking {{hadoop s3a}}.  I take back what I said about "not sure we really 
want it to be a built-in."  Following the recipe I described should work great. 
 Thanks!

> 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.
