stack commented on HBASE-10997:
-------------------------------
[~ndimiduk] Don't know about supercede. I missed hbase-9953. The modulo is a
bit more basic. All random read clients were picking at random from the total
namespace. The module narrows the namespace that clients operate in. If
module is 10, then all clients will pick rows in range 0-10 even though rows
might be 1M and clients 1000.
Does that supercede? The patches look to do similar things. Your size
confines where we operate in a similar way? (I can back this out np. You can
imagine why I need this).
