> hive metastore does not exit on start failure
> ---------------------------------------------
>
> Key: HIVE-13093
> URL: https://issues.apache.org/jira/browse/HIVE-13093
> 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.
