Anoop Sam John commented on HBASE-18528:
----------------------------------------
What we need is change the param type from deprecated HTableDescriptor to
TableDescriptor right? Which deprecated methods u want to remove? Ya may be
we can remove deprecated methods as we are any way breaking CP for 2.0 So lets
do all cleanup. If you see RegionObserver there may be so many APIs ready for
removal then. (But that is any way another issue)
> Support to modify TableDescriptor/ColumnFamilyDescriptor through
> MasterObserver; Or disable that.

> We are replacing the HTableDescriptor by TableDescriptor from code base. The
> TableDescriptor is designed to be a read-only object so user can't modifiy it
> through MasterObserver. HBASE-18502 change many methods of MasterObserver to
> use TableDescriptor but some deprecated methods still accept the
> HTableDescriptor. User may be confused by why some methods can't modify the
> table descriptor.
> In short, Should we allow user to modify the passed table descriptor?
> # if yes, we should introduce a mechanism that user can return a modified
> table descripror
> # if no, we should pass ImmutableHTableDescriptor to user. Or we just remove
> all methods accepting the HTableDescriptor
> Ditto for HColumnDescriptor.
