>             Project: Hive
>          Issue Type: Bug
>          Components: llap
>    Affects Versions: 2.0.0, 2.1.0

> 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.
