Pig Storage Handler: Add >=0.8.1 types, Guess right type for Key in Schema
--------------------------------------------------------------------------

                 Key: CASSANDRA-3280
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-3280
             Project: Cassandra
          Issue Type: Improvement
          Components: Contrib
    Affects Versions: 0.8.6
            Reporter: Steeve Morin


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:
{{raw =  LOAD 'cassandra://ks/cf?slice_start=2.5&slice_end=5.3&comparator=DoubleType'
USING CassandraStorage() AS ();}}

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}}
!
