[jira] [Updated] (SPARK-30055) Allow configurable restart policy of
driver and executor pods
[ https://issues.apache.org/jira/browse/SPARK-30055?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Kevin Hogeland updated SPARK-30055:
-----------------------------------
Description:
The current Kubernetes scheduler hard-codes the restart policy for all pods to be "Never". To restart a failed application, all pods have to be deleted and rescheduled, which is very slow and clears any caches the processes may have built. Spark should allow a configurable restart policy for both drivers and executors for immediate restart of crashed/killed drivers/executors as long as the pods are not evicted. (This is not about eviction resilience, that's described in this issue: SPARK-23980)
Also, as far as I can tell, there's no reason the executors should be set to never restart. Should that be configurable or should it just be changed to Always?
