Description
It is not currently possible to output records to more than one column family in a single reducer. Considering that writing values to Cassandra often involves multiple column families (i.e. updating your index when you insert a new value), this seems overly restrictive. I am submitting a patch that moves the specification of column family from the job configuration to the write() call in ColumnFamilyRecordWriter.
