Duo Zhang commented on HBASE-17595:
-----------------------------------
I've done some experiment and found a suitable way to fix the problem, both
server side and client side. But for client side, as HBASE-15484 added more
logics for handling partial results, it is a bit awkward that we need to
implement the same logic for both sync client and async client but with
different ways. So I plan to address HBASE-17740 first, and refactor the sync
client to also use ScanResultCache to deal with partial results. And then back
to this issue.
Thanks.

> The partial result support is marked as a 'TODO' when implementing
> HBASE-17045. And when implementing HBASE-17508, we found that if we make
> small scan share the same logic with general scan, the scan request other
> than open scanner will not have the small flag so the server may return
> partial result to the client and cause some strange behavior. It is solved by
> modifying the logic at server side, but this means the 1.4.x client is not
> safe to contact with earlier 1.x server. So we'd better address the problem
> at client side. Marked as blocker as this issue should be finished before any
> 2.x and 1.4.x releases.
