Amareshwari Sriramadasu commented on HIVE-4115:
-----------------------------------------------
The branch HIVE-4115 is ready for review. Also, created the phabricator entry.
Changes include :
* ql/src/java/org/apache/hadoop/hive/ql/cube/metadata/ has classes for Cube
Metastore adn CubeMetastoreClient.java has the api to create cube, fact and
dimension tables.
* ql/src/java/org/apache/hadoop/hive/ql/cube/parse/ has code for validating the
cube ql and converting the cube ql to HQL involving final storage tables
* ql/src/java/org/apache/hadoop/hive/ql/cube/processors/CubeDriver.java is the
entry point for the cube query. If query start with 'cube', it will be
processed by CubeDriver.
Will add Cube DDL in a followup jira.
