> I have experienced problem with queriing UDTs stored with some not filled attributes through new java driver 2.1. I tried to query them in cqlsh too and it failed. I tried to simulate it again with fresh C* directly in cqlsh and it seems it has problems in some cases. I have tested it with UDT defined as (a ascii, b ascii, c ascii, d ascii, e ascii, f ascii, g ascii). 
> Few observations:
> {noformat}
> Store {a:'a'} is ok, it returns {a: 'a', b: '', c: '', d: '', e: '', f: '', g: ''}
> Store {a:'a', b:'b', c:'c', d:'d', e:'e', f:'f', g:'g'} is ok, returns all filled.
> Store {a:'a',  g:'g'} fills a only.
> Store {a:'a', b:'b', d:'d', e:'e', f:'f', g:'g'} (missing c) failed on load.
> Store {a:'a', f:'f', g:'g'} fills just a. 
> Store {f:'f',g:'g'} nothing filled
> Store {e:'e',f:'f',g:'g'} failed on load.
