> Various patches in the Pig Storage Handler:
> - correctly guess the right Pig type for the Row Key
> - add support for FloatType, DoubleType, -UUIDType (as String) and DateType (as time
epoch)- (removed in v2 because it would break when storing data back in Cassandra)
> - add support to specify correct type comparator in SlicePredicate
> *SlicePredicate comparator:*
> For instance:
> {quote}
> {{raw =  LOAD 'cassandra://ks/cf?slice_start=2.5&slice_end=5.3&comparator=DoubleType'
USING CassandraStorage() AS ();}}
> {quote}
> It's an optional parameter. If it's not present, it will default to BytesType. Which
mean you must use hex strings.
> Hence {{slice_start=00&slice_end=FF}} isn't the same as {{slice_start=00&slice_end=FF&comparator=AsciiType}}
