Namit Jain commented on HIVE-1918:
----------------------------------

Tasks only add them when they may be available at compile time - for example, in case of dynamic
partitions.
Semantic Analyzer is supposed to add them

> 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.
