----------------------------------------------
Summary: Streamline core to shim update on allocation change
Key: YUNIKORN-462
URL: https://issues.apache.org/jira/browse/YUNIKORN-462
Project: Apache YuniKorn
Issue Type: Improvement
Components: core - scheduler, shim - kubernetes
Reporter: Wilfred Spiegelenburg
Currently in the scheduler we have two updates that get send to the shim when
an allocation is added or released:
* event to shim RM event handler to allocate
* reconciler plugin to update the shim caches
Before YUNIKORN-317 one update was made in the cace the other in the scheduler.
Now they are both in the scheduler in quick succession. The cache update in the
shim is needed to make sure that the predicates are seeing the correct info.
The event does the real bind etc of the allocation on the node.
We should be able to fold the two calls into one call. However this requires
changes on both sides and might even impact the SI as it will likely become a
synced event call.
