             Summary: handle placeholder pod recovery
                 Key: YUNIKORN-497
                 URL: https://issues.apache.org/jira/browse/YUNIKORN-497
             Project: Apache YuniKorn
          Issue Type: Sub-task
          Components: core - scheduler, shim - kubernetes
            Reporter: Wilfred Spiegelenburg


When recovering a node the existing allocations are communicated via an 
si.Allocation message. The message after the changes for the interface does not 
have the placeholder information. That means recovery of placeholder would 
generate a normal allocation.

The si.Allocation object needs the same fields a the si.AllocationAsk ( 
[document|https://docs.google.com/document/d/1YpLZLqYsp5IaeEdl_AU9wZ-f16CfaaoRhZdalDP4RCg/edit?usp=sharing]
 is updated)

The shim must add the fields when it generates the existing allocation list. 
Recovery on the core side needs to reinstate the fields into the allocation 
that gets created.
