I am running Spark 2.3 job on kubernetes cluster
kubectl version
Client Version: version.Info{Major:"1", Minor:"9", GitVersion:"v1.9.3", GitCommit:"d2835416544f298c919e2ead3be3d0864b52323b", GitTreeState:"clean", BuildDate:"2018-02-09T21:51:06Z", GoVersion:"go1.9.4", Compiler:"gc", Platform:"darwin/amd64"}
Server Version: version.Info{Major:"1", Minor:"8", GitVersion:"v1.8.3", GitCommit:"f0efb3cb883751c5ffdbe6d515f3cb4fbe7b7acd", GitTreeState:"clean", BuildDate:"2017-11-08T18:27:48Z", GoVersion:"go1.8.3", Compiler:"gc", Platform:"linux/amd64"}when I ran spark submit on k8s master the driver pod is stuck in Waiting: PodInitializing state.
This is happening if I submit the jobs almost parallel i.e. submit 5 jobs one after the other.
I tried kubectl describe node on the node where the driver pod is running this is what I got ,I do see there is over-commit on resources but I expected kubernetes scheduler not to schedule if resources in node are over-committed or node is in Not Ready state, in this case node is in Ready State but I observe same behavior if node is in Not Ready state.
