Jason Brown updated CASSANDRA-2760:
-----------------------------------
Attachment: 0001-cassandra-2760.patch
Instead of trying to process an unknown column family (and exiting with an
exception), load the Descriptor at the top of the export process and check to
see if the keyspace/column family exists inside the current cassandra setup. If
not, print a warning message and exit.
