Ted Yu commented on HBASE-3609:
-------------------------------

The goal of 3609-alternate.txt is to balance the 'ages' (reflected by sum of 
region Ids) of regions across region servers.
Currently HServerLoad doesn't contain HRegionInfo information. This makes 
validating the above goal less straightforward.
