Adam Fisk commented on CASSANDRA-638:
-------------------------------------

No problem. I'm new to nosetests, though, and running nosetests 
test/system/test_server.py can't find Thrift:

ERROR: Failure: ImportError (No module named thrift.transport)

What's the best way to wire that up? I synced up my Thrift version with trunk 
and all that.

> This crops up in any call taking both a ColumnParent and a SlicePredicate, as 
> some settings apply only to Columns while others apply only to SuperColumns.
> For example, it doesn't make sense to call setColumn_names on the 
> SlicePredicate when the ColumnParent is a ColumnFamily that contains 
> SuperColumns, as the return values will be SuperColumns, not Columns. The 
> resulting error is currently difficult to decipher (16 byte UUID required).
> Similarly, I'm not sure what happens if you don't call setColumn_names on the 
> SlicePredicate in the case where you are querying a ColumnFamily with 
> Columns, although I'm guessing it returns all column names.
> Just a quick check to make sure the SlicePredicate doesn't have column names 
> set when the ColumnParent is a SuperColumnFamily, returning a more 
> informative error if so, should do the trick.
