      This is an enhancement request to add export/import features to hive.

      With this language extension, the user can export the data of the table - which may be located in different hdfs locations in case of a partitioned table - as well as the metadata of the table into a specified output location. This output location can then be moved over to another different hadoop/hive instance and imported there.

      This should work independent of the source and target metastore dbms used; for instance, between derby and mysql.

      For partitioned tables, the ability to export/import a subset of the partition must be supported.

      Howl will add more features on top of this: The ability to create/use the exported data even in the absence of hive, using MR or Pig. Please see for these details.
