[jira] [Commented] (YUNIKORN-885) Set healtch check as liveness probe

    [ https://issues.apache.org/jira/browse/YUNIKORN-885?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17458641#comment-17458641 ] 

Craig Condit commented on YUNIKORN-885:
---------------------------------------

Looking at this a little more, I'm not sure we want to use the health check probe as a liveness check. Some of the checks done recursively go through every allocation, and this can be time-consuming. On a busy cluster, this could cause K8s to find the YuniKorn pod to be unhealthy and kill it.
