Hi @jihoonson
Thanks for your detailed review. I updated the patch using your comments a
few days ago.
And I tested the partition location rule for hive. When adding partition on
managed table or external table in hive, if the partition's directory doesn't
exist, hive make the directory by force. And when dropping partition on managed
table, hive will remove the directory by force, But when dropping partition on
external table, hive will not remove the directory. If users want to remove the
directory with drop partition statement, they need to specify PURGE option. It
seems good to me because tajo partition had been made in reference to hive
partition.
