---------------------------------------------
Summary: Application health should not be affected by faulty nodes
Key: SLIDER-1246
URL: https://issues.apache.org/jira/browse/SLIDER-1246
Project: Slider
Issue Type: Bug
Affects Versions: Slider 1.0.0
Reporter: Prasanth Jayachandran
In case of a faulty node, multiple container failures will be deemed as an
application failure.
Observed this in HIVE-16927, where container failures in certain nodes brings
down entire application. Slider has to provide a way to not mark application as
unhealthy if certain threshold of containers are running. Tuning failure
threshold is not optimal as setting the correct default on large cluster is not
trivial. Beyond certain failures, slider should mark the node as unhealthy and
report that back to client/AM. Application could continue to run as long as
container request is satisfied partially (example: 80% containers are running).
