Wangda Tan commented on YARN-6619:
----------------------------------
Quickly discussed with Arun, we will keep the main logic of AMRMClientImpl
changes to make sure AMRMClient can resend estimated pending requests to RM on
RM failover.
Following changes needed:
- We don't need to increase #pending_num_allocation for a request with the same
schedulerRequestKey. Instead, we should replace #pending-ask with the new
number. And no need to check resourceSizing.
