I am suggesting setting up a whole Hive warehouse. This way your
folders will look like
All the partitions' metadata will be kept in a RDBMS, so when you
query them with Hive it will look like
select * from yourdataset where date = 2012-09-11
and it will be fast
HCatalog is a layer that provides this Hive's functionality to Pig and
MapReduce, so in Pig you can FILTER by those dates.
