>
> 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
> http://wiki.apache.org/pig/Howl/HowlImportExport for these details.
