[jira] [Resolved] (YUNIKORN-230) Incorrect application state
returned for "ws/v1/apps" REST call
[ https://issues.apache.org/jira/browse/YUNIKORN-230?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Wilfred Spiegelenburg resolved YUNIKORN-230.
--------------------------------------------
Fix Version/s: 0.10
Resolution: Fixed
The state transitions were racing between cache and scheduler. Since we have removed the cache in 0.10 this cannot happen anymore. Before that we had mitigations in place already via YUNIKORN-222.
Closing this can not happen anymore after YUNIKORN-317
