Alejandro Abdelnur commented on YARN-983:
-----------------------------------------
Do we need an additional request field to indicate we want it?
The current logic already:
* returns the AMMR token only for unmanaged AMs
* the AMRM token only when in ACCEPTED state
Typically you 'monitor' the state of your launch AM until gets to ACCEPTED they
you proceed to register, thus effectively the AMRM token will be returned only
once.
Plus, unmanaged AMs need the AMRM token, so asking them to say they want it
seems a bit redundant.
> ApplicationReport can return tokens only when users asks for it explicitly
