> LLAP should detect all nodes down state and stop issuing queries

> Key: HIVE-12659
> URL: https://issues.apache.org/jira/browse/HIVE-12659
> Project: Hive
> Issue Type: Bug
> Components: llap
> Affects Versions: 2.0.0, 2.1.0
> Reporter: Prasanth Jayachandran
>
> I ran a simple query with 1 task in llap and for some reason llap daemon was
> down (all nodes down scenario). But queries got submitted repeatedly to the
> daemon and got killed by tez AM infinitely. Single task got killed over 20
> times and had to ctrl + c. We need to detect all nodes down scenarios (using
> Zookeeper?) and notify the client of the scenario and fail early.
