Andrew Purtell commented on HBASE-13691:
----------------------------------------

Can you provide more information on what your client code is doing? We cache 
values from Configuration in Connection so Connection#getTable can be 
"flyweight". See HBASE-12128. Was backported to 0.98 in HBASE-12604. Perhaps 
your code is not using HConnection#getTable. You'll need to use so-called 
'unmanaged' connections. Or, perhaps we've accidentally undone this 
optimization.
