Alejandro Abdelnur commented on YARN-937:
-----------------------------------------
[~bikassaha], in the way I've using unmanaged AM I have a running service that
hosts the AM without forking a process. IMO, this is the powerful thing about
unmanaged AMs. If I would be to fork a new process to run the AM, why would I
just use a managed AM.
[~daryn], the AM launcher, after creating an APP, forks a process to register
it to the schedulers, the new process does not have the launch context thus we
need the token file in this case.
