>             Project: Hive
>          Issue Type: Bug
>          Components: Hive, Metastore
>    Affects Versions: 3.0.0
>            Reporter: Alexander Kolbasov
>            Assignee: Alexander Kolbasov

> I initially noticed this problem in Apache Sentry - see SENTRY-1960. Hive has 
> the same issue. DataNucleus uses SEQUENCE table to allocate IDs which 
> requires raw locks on multiple tables during transactions and this creates 
> scalability problems. 
> Instead DN should rely on DB auto-increment mechanisms which are much more 
> scalable.
> See SENTRY-1960 for extra details.
