> 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).
