在将 Spark 应用程序提交到 Kubernetes 时将其放置在哪里？

Question

我有与本主题相同的情况。 Spark on K8s - getting error: kube mode not support referencing app depenpendcies in local

我从容器运行 Spark。 https://github.com/gettyimages/docker-spark/blob/master/Dockerfile

bin/spark-submit \
--master k8s://https://kubernetes:6443 \
--deploy-mode cluster \
--name spark-pi \
--class org.apache.spark.examples.SparkPi \
--conf spark.kubernetes.namespace=spark \
--conf spark.executor.instances=5 \
--conf spark.kubernetes.container.image=gcr.io/cloud-solutions-images/spark:v2.3.0-gcs \
--conf spark.kubernetes.authenticate.submission.caCertFile=/var/run/secrets/kubernetes.io/serviceaccount/k8.crt \
--conf spark.kubernetes.authenticate.driver.serviceAccountName=spark \ 
local:///usr/spark-2.3.0/examples/jars/spark-examples_2.11-2.3.0.jar

错误：

Exception in thread "main" org.apache.spark.SparkException: The Kubernetes mode does not yet support referencing application dependencies in the local file system.

那里可能的解决方案尚未完全证明。

我不知道该怎么办？怎么修？ Spark 版本 2.3.0。

我尝试在 spark/jars 中下载新版本的 spark-kubernetes jar。

复制并重命名 spark-kubernetes_2.11-2.3.1.jar -> spark-kubernetes_2.11-2.3.0.jar。

此修复后，Spark 未找到相应的 kubernetes 文件。

这是对我有用的命令：

/opt/spark/bin/spark-submit \
--class org.apache.spark.examples.SparkPi \
--master k8s://https://$KUBERNETES_SERVICE_HOST:$KUBERNETES_SERVICE_PORT \
--conf spark.kubernetes.namespace=myproject \
--deploy-mode cluster \
--conf spark.app.name=my-spark-app \
--conf spark.kubernetes.container.image=jkremser/openshift-spark:2.3-latest \
--conf spark.kubernetes.submission.waitAppCompletion=false \
--conf spark.kubernetes.driver.label.radanalytics.io/app=my-spark-app \
--conf spark.driver.cores=0.100000 \
--conf spark.kubernetes.driver.limit.cores=200m \
--conf spark.driver.memory=512m \
--conf spark.kubernetes.authenticate.driver.serviceAccountName=spark-operator \
--conf spark.kubernetes.driver.label.version=2.3.0 \
--conf spark.kubernetes.executor.label.sparkoperator.k8s.io/app-name=my-spark-app \
--conf spark.executor.instances=1 \
--conf spark.executor.cores=1 \
--conf spark.executor.memory=512m \
--conf spark.kubernetes.executor.label.version=2.3.0 \
--conf spark.jars.ivy=/tmp/.ivy2 \
local:///opt/spark/examples/jars/spark-examples_2.11-2.3.0.jar

确保/usr/spark-2.3.0/examples/jars/spark-examples_2.11-2.3.0.jar 文件存在于容器映像中（在您的情况下为gcr.io/cloud-solutions-images/spark:v2.3.0-gcs），因为它不应指向本地文件，而是指向容器中的文件。

你可以这样做：

docker run --rm -ti gcr.io/cloud-solutions-images/spark:v2.3.0-gcs sh

并检查那里有什么（带有示例的罐子在哪里）。

祝你好运。
