Toshihiro Suzuki commented on HBASE-12602:
------------------------------------------

[~apurtell] Thank you for your co-operation :)

[~stack] Thank you for your reply. 
To implement Iterator<Result>, I have to remove "throws IOException" from next(). 
It is not good idea for compatibility.
So I tried to add hasNext() to ResultScanner like patch(master.patch).
But It always needs to pre-read result.
I think it is not good idea.
Thank you.

> Currently, we can't call hasNext() from ResultScanner directly. I think It is convenient that ResultScanner implements Iterator.
