Namit Jain commented on HIVE-1918: ---------------------------------- Please file bugs for the above cases - The changes for import look fine. You also need to make similar changes for export. > 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 > Assignee: Krishna Kumar > Attachments: HIVE-1918.patch.1.txt, HIVE-1918.patch.2.txt, > HIVE-1918.patch.3.txt, HIVE-1918.patch.txt, hive-metastore-er.pdf > > > 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. - For more information on JIRA, see: http://www.atlassian.com/software/jira
