--------------------------------------------
Summary: 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.
