Krishna Kumar commented on HIVE-1918: ------------------------------------- Ok. Will take of this via a delegating ctor. A process question: I guess I should wait for more comments from other reviewers before I create another patch in case if others are reviewing the current patch? > Add export/import facilities to the hive system > ----------------------------------------------- > > Key: HIVE-1918 > URL: https://issues.apache.org/jira/browse/HIVE-1918 > Project: Hive > Issue Type: New Feature > Components: Query Processor > Reporter: Krishna Kumar > Attachments: HIVE-1918.patch.txt > > > 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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
