FAQ
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
