Pengcheng Xiong updated HIVE-15828:
-----------------------------------
    Target Version/s: 3.0.0  (was: 2.2.0)

> LLAP: Create root path of znode in init/start of registry service

>                 Key: HIVE-15828
>                 URL: https://issues.apache.org/jira/browse/HIVE-15828
>             Project: Hive
>          Issue Type: Bug
>          Components: llap
>    Affects Versions: 2.2.0
>            Reporter: Prasanth Jayachandran

> When there are no llap daemons running, if getInstances() in registry service is invoked
this can result in InvalidACLException since no daemons created zpath yet. The root path will
not exist when instance cache populates entries under root path. If the root path creation
is moved to init/start then getInstances() can return empty instead of failing with exception.
