             Summary: Hive Snapshots - Metadata recovery (tightly coupled with HDFS data recovery)
                 Key: HIVE-9637
                 URL: https://issues.apache.org/jira/browse/HIVE-9637
             Project: Hive
          Issue Type: New Feature
          Components: Database/Schema, SQL
    Affects Versions: 0.14.0
         Environment: HDP 2.2
            Reporter: Hari Sekhon


Feature request to add Hive HQL Snapshots against tables / databases that save the Hive metadata, analagous to HDFS snapshots for storage.

Currently HDFS snapshots do not address the loss of Hive Metadata if a Hive user were to drop a table - it would need to be re-entered manually from HQL scripts as well as HDFS snapshot data restored.

Hive Snapshots should ideally be tied together with HDFS snapshots so a single HQL command would trigger a simulatenous snapshot of the table HDFS data and Hive Metadata

These snapshots should be visible from Hive shell and able to restore both HDFS data and Hive Metadata in a single Hive command also.
