I can think of two approaches, one is to use hbase and use hbasestoragehandler in hive to read the data, handling hierarchical structures is easier in hbase, or in hive just store the data from left to right in a single row with flexible number of columns. You can also store it in json or xml and use serd to read the data in either columnar or row format. I'm sure there are other ways too.
