huzheng commented on HBASE-16886:
---------------------------------
[~tedyu][~zghaobac] Thanks for your reply.
patch v2 refactor prepare() and locateInRegions() method , because
SmallReversedScannerCallable inherit SmallScannerCallable.
As [~zghaobac] said, if SmallReversedScannerCallable inherit
ReversedScannerCallable , we do not need to refactor prepare() and
locateInRegions() , we only need to override rpcCall() method once. so I
made patch v3.
The v3 patch seems more clear .
> hbase-client: scanner with reversed=true and small=true gets no result
