Subject Spark 2.3 Kubernetes error
Date Thu, 05 Jul 2018 12:49:33 GMT
Hello,



When I’m trying to set below options to spark-submit command on k8s Master
getting below error in spark-driver pod logs



--conf spark.executor.extraJavaOptions=" -Dhttps.proxyHost=myhost
-Dhttps.proxyPort=8099 -Dhttp.useproxy=true -Dhttps.protocols=TLSv1.2" \

--conf spark.driver.extraJavaOptions="--Dhttps.proxyHost=myhost
-Dhttps.proxyPort=8099 -Dhttp.useproxy=true -Dhttps.protocols=TLSv1.2" \



But when I tried to set these extraJavaoptions as system.properties in the
spark application jar everything works fine.
