Question

在我的Cluster Kubernates中，我的spark提交产生了此错误：

Caused by: io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection refused: 
 localhost/127.0.0.1:7078

“我的火花提交”的一部分是：

spark-submit \
    --master $K8S_MASTER_URL \
    --deploy-mode cluster \
    --conf spark.executor.instances=$N_EXECUTORS \
    --conf spark.kubernetes.container.image=$SPARK_IMAGE \
    --conf spark.kubernetes.authenticate.driver.serviceAccountName=$SPARK_SERVICE_ACCOUNT \
    --conf spark.kubernetes.node.selector.spark=true \
    --conf spark.kubernetes.container.image.pullPolicy=Always \
    --conf spark.kubernetes.namespace=$SPARK_NAMESPACE \
    --conf spark.driver.memory=$DRIVER_MEMORY \
    --conf spark.executor.memory=$EXECUTOR_MEMORY \
    --conf spark.kubernetes.driver.pod.name=dbloader-events-$TS \
    --conf spark.kubernetes.pyspark.pythonVersion="3"\
    --conf spark.executorEnv.PYSPARK_PYTHON=/usr/bin/python3 \
    --conf spark.driverEnv.PYSPARK_PYTHON=/usr/bin/python3 \
    --conf spark.driverEnv.PYTHONPATH=/usr/bin \
    --conf spark.executorEnv.PYTHONPATH=/usr/bin \
    --conf spark.driverEnv.PYSPARK_DRIVER_PYTHON=/usr/bin \
    --jars $JAR_DEPENDENCIES

使用spark-submit，我创建了一个在python中启动工作spark的pod。但是这项工作显示了提到的错误我需要帮助。
