John Vines commented on ACCUMULO-3236:
--------------------------------------

I've been thinking of it as CloneInto, but I'm not stuck to it. importFrom could work, as I see this being more similar to a bulk import than a clone.

> Currently we have the ability to clone a table, which takes all files belonging to an existing table and then makes them owned by a second, brand new table. I think there is a logic extension to this where you can add the files to an already existing table.
> One point of concern is if data is unused in existing files due to major compactions of the shared files in the source table. This can be mitigated by either chopping the files (which sorta goes against the idea of cloning) or ensuring that at source table splits exist in the destination table.
