Manual Spray

Post questions or comments on how best to manage your big data problem

I've been told many (many) times that the spray feature is just a simple file-splitting+ship-file-parts-to-slave-nodes+logical-file-entry process (that doesn't seem THAT simple to me ;)).

I was wondering if it would be possible for me to keep/create those file parts and, upon creating a new cluster, download those files parts onto the slave nodes, and manually create that logical file entry specifying where all those parts are.

I've used dfuplus to spray/despray files before and saw the savexml action there. Is it what I should use?
Would you have a snippet+explanation/blog post/pdf/anything on how to use it to re-create a logical file? (I see how to use to export the xml, but how do I create a logical file with it?)

Thanks for the help!

Have you tried the remote copy option? I believe that's what we use to move logical files from one cluster to another.
