We are trying to run a Spark job on Kubernetes cluster. The Spark job needs to talk to some services external to the Kubernetes cluster through a proxy server. We are setting the proxy by setting the extraJavaOptions like this
--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" \ The problem is that this forces all communication to go through the proxy. This includes the communication between the pods, and between pod and K8s master. The proxy is blocking the the traffic that is supposed to stay within the cluster, and the job fails We should be setting noproxy so intra-k8s communication doesn’t go through the proxy. The problem is that we don’t know what to put in noproxy. Has anyone run Spark on K8s behind proxy? ________________________________________________________ The information contained in this e-mail is confidential and/or proprietary to Capital One and/or its affiliates and may only be used solely in performance of work or services for Capital One.
