Stu Hood updated CASSANDRA-1315:
--------------------------------

    Attachment: 0002-Allow-multiple-mutations-per-key-to-arrive-during-in.patch

Add 0002 to allow mutations for keys to arrive during separate write calls, rather than clobbering
existing keys.

> ColumnFamilyOutputFormat currently takes IColumns as its input, meaning that users need
to understand Cassandra's internals reasonably well in order to use it, and need to hardcode
things like the comparator type and clock type into their MapReduce jobs.
> Instead, CFOutputFormat should take either Thrift or Avro objects, which are familiar
interfaces for users.
