>             Project: Hive
>          Issue Type: Bug
>          Components: Metastore
>    Affects Versions: 0.13.1, 1.0.0, 1.1.1, 1.2.1
>            Reporter: Thejas M Nair
>            Assignee: Thejas M Nair
>
> If metastore startup fails for some reason, such as not being able to access the database, it fails to exit. Instead the process continues to be up in a bad state.
> This is happening because of a non daemon thread.
