stack commented on HBASE-4991:
------------------------------

bq. For successive regions R1, R2 and R3, if we delete R2, we can change the 
end key of R1 to be the original end key of R2 and drop region R2 directly.

Changing the end key of R1 to be the end key of R2 will require creating a new 
region R1'; we'll have to close R1 and R2 and delete both (after moving the R1 
data to R1').
                
> Provide capability to delete named region
