Rick Shaw updated CASSANDRA-3421:
---------------------------------
Attachment: 3421.txt
This occurs because the {{compose}} method in {{DecimalType}} does not protect
itself by checking for an empty {{ByteBuffer}} argument which is what occurs
if a single item is in the CF.
> Can create a table with DecimalType comparator but CQL explodes trying to
> actually use it.
