Arun C Murthy commented on MAPREDUCE-3098:
------------------------------------------
bq. Apologies if I am giving an impression of creating a storm. But honestly
all of this was thought through earlier end-to-end and I firmly belive that the
current states and records represent the correct abstraction.
Healthy back & forth is good. Helps everyone - don't worry about it.
Seems to me that there are 2 states:
a) State of the AM _attempt_
b) State of the application itself.
Oh, we also have 'diagnostics', more on this later.
So, the crux is: forcing application writers to come up with Strings to
describe their state seems a poor api/abstraction.
Can we do better?

> Currently, an application report received by the client from the RM/ASM for a
> given application returns the status of the application master. It does not
> return the status of the application i.e. whether that particular job
> succeeded or failed.
> The AM status would be one of FINISHED (SUCCEEDED should be renamed to
> FINISHED as AM state does not indicate overall success/failure), FAILED or
> KILLED.
> The final state sent by the AM to the RM in the
> FinishApplicationMasterRequest should be exposed to the client as
> ApplicationState.
