> 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).
