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. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
