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. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
