> Key: HIVE-7353
> URL: https://issues.apache.org/jira/browse/HIVE-7353
> Project: Hive
> Issue Type: Bug
> Components: HiveServer2
> Affects Versions: 0.13.0
> Reporter: Vaibhav Gumashta
> Assignee: Vaibhav Gumashta
> Fix For: 0.14.0
>
> Attachments: HIVE-7353.1.patch, HIVE-7353.2.patch, HIVE-7353.3.patch
>
>
> While using embedded metastore, while creating background threads to run
> async operations, HiveServer2 ends up creating new instances of
> JDOPersistanceManager rather than using the one from the foreground (handler)
> thread. Since JDOPersistanceManagerFactory caches JDOPersistanceManager
> instances, they are never GCed.
