Lars Hofhansl commented on HBASE-2214:
--------------------------------------

Actually in order to make this work, we'd have make sure an older server can 
read the Scan object from newer client, so we cannot do this (since an old 
servers are deployed already).

If there is no way to do this without changing the version of the Scan version 
I suggest we defer this until 0.96.

                
> Do HBASE-1996 -- setting size to return in scan rather than count of rows --

> The notion that you set size rather than row count specifying how many rows a 
> scanner should return in each cycle was raised over in hbase-1966.  Its a 
> good one making hbase "regular" though the data under it may vary.  
> HBase-1966 was committed but the patch was constrained by the fact that it 
> needed to not change RPC interface.  This issue is about doing hbase-1966 for 
> 0.21 in a clean, unconstrained way.
