>             Project: Hive
>          Issue Type: Bug
>    Affects Versions: All Versions
>         Environment: Hadoop 3.1(1700+ nodes)
> YARN 3.1 (with timelineserver enabled,https enabled)
> Hive 3.1 (15 HS2 instance)
> 60000+ YARN Applications every day

>            Priority: Critical

> So when YARN use Https, MergeFileTask causes more and more Threads named “ReloadingX509TrustManager”
in HiveServer2。The threads named “ReloadingX509TrustManager” does not interrupt,and
HS2 becomes abnormal。
> In MergeFileTask.execute(DriverContext driverContext) ,a Jobclient created but not closed。The
issue cause above。
