Carl Steinbach commented on HIVE-1918:
--------------------------------------
I discarded my reviewboard request after Krishna's original request.
Unfortunately this doesn't appear to prevent people from commenting on it, and
reviewboard won't let me delete the request outright.
Please review the patch here: [https://reviews.apache.org/r/430/]

> 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.
