Possible to add new partition columns to existing Hive tables?

Hello all,

Is it possible to add new partition columns to existing Hive tables with
data already loaded in them?

For example, if I have a table that already has a partition column for
"date" and I wanted to add a new partition column for "hour of day" -- would
it be possible without reloading all of the data currently stored in the
table?

Thanks!

Ryan
