Pengcheng Xiong updated HIVE-15163:
-----------------------------------
    Target Version/s: 3.0.0  (was: 2.2.0)

> LLAP Finishable state updates may not go to daemons restarted on the same node

>                 URL: https://issues.apache.org/jira/browse/HIVE-15163
>             Project: Hive

> Finishable state updates only go out to nodes when the source state changes. When a node
goes down, and comes back up on the same port - updates which had been sent to the old node
will not be sent to the new node. This could lead to a fragment being in a permanent preemptable
state, and lead tp starvation on busy clusters.
