没有安装Anaconda,一切正常.也就是说,我可以导入上面提到的包.但安装Anaconda后,我无法导入相同的软件包.这是我得到的错误: -

>>> import numpy
Traceback (most recent call last):

我正在尝试使用 intellij 在 spark 上运行 Scala 代码。

Scala 代码

import scala.collection.JavaConverters._
import org.apache.spark.SparkContext
import org.apache.spark.SparkConf
object WordCount {
  def main(args: Array[String]): Unit = {
    val sc = new SparkContext(new SparkConf().setAppName("anything").setMaster("localhost"))
    println("Hello World!")
  } 
}

我正在尝试使用Google Kubernetes Engine运行apache ignite集群。

遵循本教程之后，这里是一些yaml文件。

首先，我创建一个服务 -ignite-service.yaml

apiVersion: v1
kind: Service
metadata:
  # Name of Ignite Service used by Kubernetes IP finder. 
  # The name must be equal to TcpDiscoveryKubernetesIpFinder.serviceName.
  name: ignite
  namespace: default
spec:
  clusterIP: None # custom value.
  ports:
    - port: 9042 # custom value.
  selector:
    # Must be equal to one of the labels set in Ignite pods'
    # deployement configuration.
    app: ignite

kubectl create -f ignite-service.yaml

其次，为我的ignite节点ignite-deployment.yaml创建一个部署

用于Ignite Pod部署的Kubernetes配置示例。
