Chia-Ping Tsai commented on HBASE-19550:
----------------------------------------
Perhaps it would be better to wrap all cells in mutation to be of ExtendedCell
since wrapping the mutation in cp layer is ugly and may get cryptic in the
future. Also, cp user are allowed to add their mutation via
{{MiniBatchOperationInProgress}] so wrapping only our mutation passed to cp
user is not a total solution.

> We assume all cells in server are of ExtendedCell. However, cp user can add
> their cell impl via Put#add(Cell) in observer. That will cause
> UnsupportedOperationException when rs try to update the cell's timestamp and
> seq Id. We should do something for cp user...For example, wrap the passed
> cells to be a extendcell type.
