Sergey Shelukhin commented on HBASE-8430:
-----------------------------------------

advance() in scanner/decoder currently doesn't throw any exception. Not sure if 
it should throw CSE or let the original propagate. Some other IOException 
subclasses like EOFException could be useful.
                
> Cell decoder/scanner/etc. should not hide exceptions

> Cell scanner, base decoder, etc., hide IOException inside runtime exception. 
> This can lead to unexpected behavior because a lot of code only expects 
> IOException. There's no logical justification behind this hiding so it should 
> be removed before it's too late (the sooner we do it the less throws 
> declarations need to be added)
