1. then the spark namespace will be used by default. This is a simpler alternative than hosting the Spark History Server yourself! This could mean you are vulnerable to attack by default. ensure that once the driver pod is deleted from the cluster, all of the application’s executor pods will also be deleted. It can be found in the kubernetes/dockerfiles/ Kubernetes (also known as Kube or k8s) is an open-source container orchestration system initially developed at Google, open-sourced in 2014 and maintained by the Cloud Native Computing Foundation. Similarly, the do not provide a scheme). By default, the driver pod is automatically assigned the default service account in In this Apache Spark Tutorial, you will learn Spark with Scala code examples and every sample example explained here is available at Spark Examples Github Project for reference. being contacted at api_server_url. To get some basic information about the scheduling decisions made around the driver pod, you can run: If the pod has encountered a runtime error, the status can be probed further using: Status and logs of failed executor pods can be checked in similar ways. In cluster mode, if this is not set, the driver pod name is set to "spark.app.name" Active 1 month ago. will be the driver or executor container. do not provide It offers many features critical to stability, security, performance, and scalability, like: Kubernetes has become the standard for infrastructure management in the traditional software development world. Spark creates a Spark driver running within a. Docker is a container runtime environment that is You submit a Spark application by talking directly to Kubernetes (precisely to the Kubernetes API server on the master node) which will then schedule a pod (simply put, a container) for the Spark driver.
