[jira] [Updated] (HIVE-15342) Add support for primary/foreign keys in HBase metastore

     [ https://issues.apache.org/jira/browse/HIVE-15342?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Alan Gates updated HIVE-15342:
------------------------------
    Attachment: HIVE-15342.patch

This patch adds two new columns in the catalog column column family in the tables_table, one for the primary key and one for all foreign keys.  Putting it in the tables_table allows us to automatically drop the keys when the table is dropped, and in the future will allow a single call to fetch table and keys efficiently.

> When HIVE-13076 was committed the calls into the HBase metastore were stubbed out.  We need to implement support for constraints in the HBase metastore.
