> LLAP IO: better refcount management
> -----------------------------------
>
> Key: HIVE-16778
> URL: https://issues.apache.org/jira/browse/HIVE-16778
> Project: Hive
> Issue Type: Bug
> Reporter: Sergey Shelukhin
> Assignee: Sergey Shelukhin
> Attachments: HIVE-16778.patch, HIVE-16778.patch
>
>
> Looks like task cancellation can close the UGI, causing the background thread
> to die with an exception, leaving a bunch of unreleased cache buffers.
> Overall, it's probably better to modify how refcounts are handled - if
> there's some bug in the code we don't want to leak them.
