Brandon Williams updated CASSANDRA-2777:
----------------------------------------

    Attachment: 2777.txt

Patch implements the LoadMetadata interface.  Doesn't handle supercolumns since 
we already punted on deserializing those.

> Pig storage handler should implement LoadMetadata

> The reason for this is many builtin functions like SUM won't work on longs 
> (you can workaround using LongSum, but that's lame) because the query planner 
> doesn't know about the types beforehand, even though we are casting to native 
> longs.
> There is some impact to this, though.  With LoadMetadata implemented, 
> existing scripts that specify schema will need to remove it (since LM is 
> doing it for them) and they will need to conform to LM's terminology (key, 
> columns, name, value) within the script.  This is trivial to change, however, 
> and the increased functionality is worth the switch.
