----------------------------------------------

I am having issues with loading set types into Pig, and with reverting changes
to this story, it works as expected.
Values of set types are not loading correctly from Cassandra (cql3 table,
Native protocol v3) into Pig using CqlNativeStorage.
When using Cassandra version 2.1.0 only empty values are loaded, and for newer
versions (2.1.1 and 2.1.2) the following error is received:
org.apache.cassandra.serializers.MarshalException: Unexpected extraneous bytes
after set value
at
org.apache.cassandra.serializers.SetSerializer.deserializeForNativeProtocol(SetSerializer.java:94)
Note, that it works correctly for version 2.1.0-rc4 and CqlStorage.
