Have been trying to import data into multiple Column Families through a Hadoop job. Was able to use CqlOutputFormat to move data to a single column family, but don't think this supports imports to multiple column families. From some searching saw that CqlBulkOutputformat has support to write to multiple column families, but have not been able to get it working. Could not find any examples on this. Would be great if someone could help me with an example of using CqlBulkOutputFormat with MultipleOutputs .
