Subject [jira] [Commented] (SPARK-27812) kubernetes client import non-daemon thread which block jvm exit.
Date Mon, 15 Jul 2019 13:14:00 GMT

    [ https://issues.apache.org/jira/browse/SPARK-27812?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16885219#comment-16885219

Edwin Biemond commented on SPARK-27812:
---------------------------------------

for SPARK-27927 indeed all is fine on spark 2.4.3 when I revert SPARK-26742 commit ->
k8s back to kubernetes-client-3.0.0.jar & kubernetes-model-2.0.0.jar

I understand we need to do patching but spark 2.4.3 is maintenance release and this should
never happen. 

especially If we not even patch jackson-core to 2.9.9 because of security risks 

 

This has to be done in 3.0.0 and have a proper fix for this blocking threads plus all the
time to resolve this.
