--------------------------------
Summary: External partition
Key: HIVE-3586
URL: https://issues.apache.org/jira/browse/HIVE-3586
Project: Hive
Issue Type: New Feature
Components: Query Processor
Reporter: Ning Zhang
External tables are extremely useful when two or more tables share the same
data but would like to avoid the data copy and ownership conflicts. We found it
useful to extend the "external" concept to the partition level: some partitions
of a managed table could be external, so that dropping an external partition
won't delete the data.
