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

             Summary: Replace String tableName arguments with TableHandle
                 Key: ACCUMULO-3238
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-3238
             Project: Accumulo
          Issue Type: Improvement
          Components: client
            Reporter: John Vines


All of our client operations work by table name. This present awkward cases around renames.
A solution to this is making all operations work around table IDs, but this isn't user friendly.
A middle ground is introducing a TableHandle, which is a container for the user to use, with
the implication that if a rename happens, the operations will follow the table. This is similar
to how filesystems deal with renames.

This way we have the translation between table name->id done VERY early on and done explicitly
to the users knowledge so they can make guarantees about operations.

I would see there being an operation added for getTableHandle which takes the name and then
that handle is used for all future operations.

By putting things in a TableHandle, we can have a minor first pass which ges the API in place
and then we can work on ensuring no name->id mapping occurs deeper in the server to help
make sure things are consistent.
