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

             Summary: Clone table into an existing table
                 Key: ACCUMULO-3236
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-3236
             Project: Accumulo
          Issue Type: Bug
          Components: client, tserver
            Reporter: John Vines
             Fix For: 1.7.0


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.
