Hello,
I made the following change to the 5.6.6-labs-june-2012 codebase to
get the partition engine error recovery to work with TokuDB.  The code
is trying to drop a successfully added key.  It would be nice to
supply the key info for the table with the new key in it, which is
what the change does.

Thanks
