apache-spark - 如何修复 'java.lang.NoClassDefFoundError: io/fabric8/kubernetes/api/model/apps/Deployment'

Question

我一直在尝试在Kubernetes集群的Zeppelin(v0.7.3)上集成spark解释器。但是，由于在服务器https://issues.apache.org/jira/browse/SPARK-28921上具有k8s版本1.13.10的复杂性

我需要将spark k8s-client升级到v4.6.1，如此处https://github.com/GoogleCloudPlatform/spark-on-k8s-operator/issues/591#issuecomment-526376703所示

但是，当我尝试在zeppelin-ui上执行spark命令sc.version时，我得到:

ERROR [2019-10-25 03:45:35,430] ({pool-2-thread-4} Job.java[run]:181) - Job failed
java.lang.NullPointerException
 at org.apache.zeppelin.spark.Utils.invokeMethod(Utils.java:38)

    at org.apache.zeppelin.spark.SparkInterpreter.open(SparkInterpreter.java:843)
    at org.apache.zeppelin.interpreter.LazyOpenInterpreter.open(LazyOpenInterpreter.java:70)

这是我拥有的spark-submit配置，但是我不认为错误是由这些引起的(因为我之前已经运行过这些并且它们可以正常工作)

spark.kubernetes.driver.docker.image=x
spark.kubernetes.executor.docker.image=x
spark.local.dir=/tmp/spark-local
spark.executor.instances=5 
spark.dynamicAllocation.enabled=true
spark.shuffle.service.enabled=true
spark.kubernetes.shuffle.labels="x"
spark.dynamicAllocation.maxExecutors=5
spark.dynamicAllocation.minExecutors=1 
spark.kubernetes.docker.image.pullPolicy=IfNotPresent
spark.kubernetes.resourceStagingServer.uri="http://xxx:xx"

我曾尝试将spark-k8s客户端降级为3.x.x，直到4.0.x，但出现HTTP错误。因此，我决定坚持使用v4.6.1。打开齐柏林飞艇解释器日志，我发现以下堆栈跟踪:

我希望运行以下命令:

%spark
%sc.version 

附言这是我在这里的第一篇文章，因此，如果我没有遵守某些规则，请纠正我。谢谢!

经过同事的严格研究和帮助，我能够验证Kubernetes-model-v2.0.0上不存在io/fabric8/kubernetes/api/model/apps/Deployment。将jar升级到v3.0.0可以解决此问题。
