Zheng Hu commented on HBASE-18160:
----------------------------------

bq. I'm thinking of another optimization for filterlist with MUST_PASS_ONE. If 
all filter in the filterlist return NEXT_ROW/NEXT_COL, can we return 
NEXT_ROW/NEXT_COL?
I created HBASE-18416 for it. 
bq.  But the optimized way would be return a highest key hint of all these 
returned hints.
I created HBASE-18414 for it.
bq. In case of MUST_PASS_ALL operator also, we don't handle 
INCLUDE_AND_SEEK_NEXT_ROW.
You are right, Let me fix it.
bq. A small reset one liner can avoid such a possible issue! 
Got it,  Let me fix it.

> As HBASE-17678 said, there are two problems in FilterList.filterKeyValue 
> implementation: 
> 1.  FilterList did not consider INCLUDE_AND_SEEK_NEXT_ROW case( seems like 
> INCLUDE_AND_SEEK_NEXT_ROW is a newly added case, and the dev forgot to 
> consider FilterList), So if a user use INCLUDE_AND_SEEK_NEXT_ROW in his own 
> Filter and wrapped by a FilterList,  it'll  throw  an 
> IllegalStateException("Received code is not valid."). 
> 2.  For FilterList with MUST_PASS_ONE,   if filter-A in filter list return  
> INCLUDE and filter-B in filter list return INCLUDE_AND_NEXT_COL,   the 
> FilterList will return  INCLUDE_AND_NEXT_COL finally.  According to the 
> mininal step rule , It's incorrect.  (filter list with MUST_PASS_ONE choose 
> the mininal step among filters in filter list. Let's call it: The Mininal 
> Step Rule).
