PrabhuJoseph opened a new pull request, #22870:
URL: https://github.com/apache/flink/pull/22870
## What is the purpose of the change
Currently, Blocklist unblockResources does not update the existing pending
resource request from YARN/K8S. It updates only for the new resource requests.
The existing pending resource requests are not scheduled on the nodes which are
unblocked. This Patch updates the pending resource requests.
## Brief change log
1. _unblockResources_ method is added in _ResourceManagerDriver_ interface
which both _YarnResourceManagerDriver_ and _KubernetesResourceManagerDriver_
implements.
2. _ActiveResourceManager_ invokes the _unblockResources_ in
_ResourceManagerDriver_ when _BlockListHandler_ removes the timedout blocked
nodes.
3. _YarnResourceManagerDriver_ calls the _tryUpdateApplicationBlockList_ to
update YARN with new block list details.
4. _KubernetesResourceManagerDriver_ gets the pending pod with node affinity
notin set to any of the unblocked node and stops and reschedule.
## Verifying this change
1. _YarnResourceManagerDriverTest_#_testUpdateBlocklist_
2. _KubernetesResourceManagerDriverTest_#_testUnblockResources_
