Steeve Morin updated CASSANDRA-3280:
------------------------------------
Description:
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)
- 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}} !
