---------------------------------------

Thanks [~stevel@apache.org] for reporting and [~gabor.bota] for the patch!

I am not that familiar with this part of the code, but the patch looks good to me.

> If you have s3guard set up with a table name and a region, then s3guard init will automatically
create the table, without you specifying a bucket or URI.
> I had expected the command just to print out its arguments, but it actually did the init
with the default bucket values
> Even worse, `hadoop s3guard destroy` will destroy the table. 
> This is too dangerous to allow. The command must require either the name of a bucket
or an an explicit ddb table URI
