Junping Du commented on YARN-3866:
----------------------------------
bq. As Wangda Tan mentioned, the ApplicationMasterProtocol is a lower level
protocol and end user applications should be using the AMRMClient.
I agree most applications are supposed to use AMRMClient (except MR). However,
ApplicationMasterProtocol is still marked as public for using by downstream
projects (open or closed sourced). Unless this API is marked as restricted to
MR only, there should be 0 assumption for users on how to use it.
bq. Given that the increase/decrease resources are not available in any current
version of hadoop.and given that YARN-5221 was raised to unify all container
updates (resources and ExecutionType etc.) into a single API, I am not in favor
of adding back the (set/get)(Increase/Decrease)(Requests/Containers) API as it
will cause problems for future upgrades, if people do start using them.
No. It is already get released in 2.7.3:
https://hadoop.apache.org/docs/r2.7.3/api/index.html. In release prospective,
all released public APIs (unless marked as unstable explicitly) are protocol
between software (and developer behind it) and users. I can understand that
public these APIs in 2.7.3 may not be intentional, but we should take response
for all sequences it could generate. We can deprecate these APIs to tell people
to use the right API. I think that is the right way to do.
