Karthik Kambatla reopened YARN-1055:
------------------------------------
Here is one use case where setting app retries alone might not be enough.
Consider jobs being run via Oozie. We want different behavior for the launched
actions in the following two scenarios:
# Without RM restart, we want to be able to set app-retries > 1 to address any
transient errors.
# On RM restart, we want Oozie launchers to be recovered, but not the already
launched actions. Otherwise, we will end up having two copies of the same
action.
Thoughts?
> App recovery should be configurable per application

> In Hadoop-1, the job recovery on JT restart is configurable per-job. For
> parity and its usefulness, we should have the same behavior in YARN as well.
