I could go either way on this issue. It is public and their are thrift stubs. http://hive.apache.org/docs/r0.6.0/api/org/apache/hadoop/hive/metastore/HiveMetaStoreClient.html. I would worry about users using RAW methods such as: add_partition(Partition new_part) Add a partition to the table. Users should try to interface through CLI | HiveServer if possible. Anything below that is "internal" IMHO, but I am guilty for using it directly. Just be warned. It changes typically without any deprecation. Edward
