>                 Key: HIVE-22103

>             Project: Hive
>          Issue Type: Task
>          Components: HiveServer2, llap
>    Affects Versions: 3.1.0
>            Reporter: Sampada Dehankar
>            Assignee: Richard Zhang
>            Priority: Major

> In Hive 3.x, Yarn-Service is used to launch llap-daemons. If a container (llap-daemon) is killed and there are pending Tez AMs, the llap-daemon container might not get launched as the available resources can be utilized by Tez AMs.
> This happens as Yarn-Service and Tez AMs both are launched with the same Yarn Application priority (0). Due to this, which of the two would get the resource is uncertain.
> In the previous versions on Hive, this issue was not present as Slider was launched with priority 1. And Tez AMs are launched with priority 0.
