Gour Saha commented on YARN-7991:
---------------------------------
[~rohithsharma], [~sunilg] and I had a discussion on this -
- Delete API is invoked from the client.
- The Service AM is not running during this time since the service is stopped.
- ATSv2 is designed to publish data within the scope of the application.
- So it won't be possible to publish data to ATSv2 from a client.
Couple of options we have now -
# UI2 can consume YARN Service GET REST API to determine if a service is in
STOPPED state or deleted, using which the Delete/Stop options can be displayed
correctly. There are some UI2 framework related changes that are required to
make this happen. The effort here is of medium size.
# ATSv2 can support publishing of data outside the scope of an application.
The effort here is pretty large.
