> CASSANDRA-5752 introduced support to thrift tables on CQLPagingInputFormat via the retrieveKeysForThriftTables() method.
> However, this method only retrieves partition keys from CFMetaData, so clustering columns are ignored.
> So, when the RowIterator tries to fetch the next page of a wide-row thrift CF, it ignores the clustering column altogether, going to the next partition token. So, only cassandra.input.page.row.size CQL rows are retrieved for each partition key.
> CqlRecordWriter had the same issue and was fixed on bcfe352ea6ed3786f274b90191f988210360689d (CASSANDRA-5718).
