Low Description
If I run the demo pig scripts, I end up with a column family with 6 fairly wide rows. If I load and dump those rows with widerows=true or set the cassandra.range.batch.size=1, the dump returns the correct values. However, if I set both of those, it does not. So in the case of a batch size of 1, wide rows support is broken.
So it's relatively simple to reproduce from the demo data:
grunt> SET cassandra.range.batch.size 1
grunt> rows = LOAD 'cassandra://PigDemo/Scores' using CassandraStorage();
grunt> dump rows;

When I try with set batch size to something higher than 1 and it works fine.
