[jira] [Created] (HIVE-15413) Primary key constraints forced to be unique across database and table names

Alan Gates created HIVE-15413:
---------------------------------

             Summary: Primary key constraints forced to be unique across database and table names
                 Key: HIVE-15413
                 URL: https://issues.apache.org/jira/browse/HIVE-15413
             Project: Hive
          Issue Type: Bug
          Components: Metastore
    Affects Versions: 2.2.0
            Reporter: Alan Gates
            Priority: Critical


In the RDBMS underlying the metastore the table that stores primary and foreign keys has it's own primary key (at the RDBMS level) of (constraint_name, position).  This means that a constraint name must be unique across all tables and databases in a system.  This is not reasonable.  Database and table name should be included in the RDBMS primary key.
