Hi @Mushtaq Rizvi, in thinking outloud, if you are looking at the Hive metastore and its running Oracle, MySQL, or MariaDB, I supposed you could create standard triggers to notify you when something changes. I know this can be done in SQL Server but I haven't explored the other RBMS options. Be careful how how this would affect performance depending on the rate of change.
I'm not aware of a solution native to Hive. Hive does not support triggers though there may be some better options once HPL/SQL is introduced into the Hive.
Please update this post if you find another solution.
