> As part of the ongoing interface abstraction work, I'm now investigating {{TableInputFormatBase}},
which has two methods that break encapsulation:
> {code}
> protected HTable getHTable();
> protected void setHTable(HTable table);
> {code}
> While these are protected methods, the base @InterfaceAudience.Public is abstract, meaning
that it supports extension by user code.
> I propose deprecating these two methods and replacing them with these four, once the
Table interface is merged:
> {code}
> protected Table getTable();
> protected void setTable(Table table);
> protected RegionLocator getRegionLocator();
> protected void setRegionLocator(RegionLocator regionLocator);
> {code}
> Since users will frequently call {{setTable}} and {{setRegionLocator}} together, it probably
also makes sense to add the following convenience method:
> {code}
> protected void setTableAndRegionLocator(Table table, RegionLocator regionLocator);
> {code}
