Craig Condit resolved YUNIKORN-2180. ------------------------------------ Fix Version/s: 1.5.0 Resolution: Fixed Merged to master. > Clean up scheduler state initialization > --------------------------------------- > > Key: YUNIKORN-2180 > URL: https://issues.apache.org/jira/browse/YUNIKORN-2180 > Project: Apache YuniKorn > Issue Type: Sub-task > Reporter: Craig Condit > Assignee: Craig Condit > Priority: Major > Labels: pull-request-available > Fix For: 1.5.0 > > > Scheduler state initialization (otherwise known as recovery) is currently > fragile and somewhat unpredictable since multiple asynchronous processes > coordinate to perform the various init tasks. > Startup initialization should be simplified to the following steps: > # Read all priority classes from the informer and register them with the > scheduler cache > # Read all nodes from the informer and register them (in a drained state) > with the scheduler core > # Read all pods from the informer and register applications and allocations > as necessary, associating existing allocations with nodes from step #2 > # Enable the nodes which were originally registered in step #2 > # Register and start Kubernetes event handlers > # Re-read priority classes from the informer and remove any that have gone > away since step #1, ensuring we don't miss priority class deletions during > init > # Re-read nodes from the informer and remove any that have gone away since > step #2, ensuring we don't miss node deletions during init > # Re-read pods from the informer and remove any that have gone away since > step #3, ensuring we don't miss pod deletions during init > Additionally, this process should be handled entirely by the scheduler > context to avoid mulitple competing concerns. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@yunikorn.apache.org For additional commands, e-mail: issues-h...@yunikorn.apache.org
