> After pulling hair out about why weird errors were happening loading data from cassandra
with seemingly irrelevant changes to the pig scripts (mostly changing the script trying to
debug other problems), it looks like the weird errors were because of the implementation we
currently have for LoadPushDaown in CassandraStorage.  Unless there is a good reason to implement
it, I feel like we should just remove the few lines that are in there until we can spend some
serious time doing an implementation of it.
