James Taylor commented on PHOENIX-4344:
---------------------------------------

Yes, you’re right - that’s one of the limitations for indexes on views - the 
DML must be done on the leaf views. If you do that, everything will just work 
(famous last words :-) ).

> Phoenix already has the ability to use MapReduce for asynchronous handling of 
> long-running SELECTs. It would be really useful to have this capability for 
> long-running DELETEs, particularly of tables with indexes where using HBase's 
> own MapReduce integration would be prohibitively complicated.
