@Jimmy
If i read the patch correctly we just add all the regions into the regiononline map.
Now if i have 4 regions for a table.
1 is assigned, 2 in the process of assigning and 1 is yet to be assigned so the table is in
ENABLING.  Now if all the regions are added to online map then how will EnableTableHandler
know that he has to assign the ones that are not assigned?
Actually HBASe-6317 tries to solve the problem that you mentioned - double assignment.
Pls correct me if am wrong Jimmy. May be am missing something in trunk after the refactorings?

> For opened region of disabled table, it should be added to online region list, and then
closed.  We should not just ignore them.
> For opened region of enabling table, it should be added to online region list, so that
we don't have to assign it again.  Without adding it to online region list, it could be double
assigned when assign it again later.
