----------------------------------------------
Summary: node removal with inflight placeholder replacement failure
Key: YUNIKORN-854
URL: https://issues.apache.org/jira/browse/YUNIKORN-854
Project: Apache YuniKorn
Issue Type: Bug
Components: core - scheduler
Affects Versions: 0.10
Reporter: Wilfred Spiegelenburg
Assignee: Wilfred Spiegelenburg
If a node gets removed while a replacement of a placeholder pod is inflight we
lose track:
* placeholder and real allocation on the same node causes the real pod to
never be allocated as the ask repeat has been decremented but the allocation is
removed being processed
* placeholder and real allocation on different nodes causes the real
allocation to be linked to a node but never bound on K8s if the placeholder
node is removed.
* placeholder and real allocation on different nodes causes a zombie
allocation on the application if the real allocation node is removed.
