[jira] [Updated] (HBASE-17595) Add partial result for small/limited scan

["Duo Zhang (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HBASE-17595?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Duo Zhang updated HBASE-17595:
------------------------------
    Priority: Major  (was: Blocker)

When implementing other stuffs for scan I found that it is not easy to make the new client compatible with an old server,,, And this is not required in our compatibility matrix. So change the priority to major instead of critical.

> 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.
