Gour Saha commented on SLIDER-950:
----------------------------------
bq. actionMultiAppStatus would do similar things as their single app origin.
the difference is it now invokes YARN API multiple times: once per app
[~thomas_liu] this will not help because invoking YARN API multiple times will
not scale either. Look at _*listDeployedInstances*_ in _SliderYarnClientImpl_.
It calls _*getApplications*_ which fetches reports of all apps of type
_*org-apache-slider*_. The current API then looks up for a specific app. We
need to leverage that to create this multi app getStatus API.
Please review that flow, as I might have missed something.
