【问题描述】：
我使用 spark-submit 直接将 Spark 应用程序提交到 Kubernetes 集群。使用以下命令：
提交 Spark
./bin/spark-submit --master k8s://https://localhost:8443
--deploy-mode cluster --name spark-pi
--class com.xxx.Main
--conf spark.executor.instances=5
--conf spark.kubernetes.container.image=spark:latest
local:///home/SparkJob_jar spark.kubernetes.file.upload.path=/opt/xxx
但我得到以下异常：
20/09/25 11:33:57 WARN Utils: Your hostname, XXXX resolves to a loopback address: 127.0.1.1; using xxx.yyy.zzz instead (on interface wlp59s0)

https://issues.apache.org/jira/browse/SPARK-31800 的帖子建议添加 spark.kubernetes.file.upload.path 来解决问题，我在提交命令中添加了它，但问题仍然存在。感谢您为找出此问题的根本原因提供的任何帮助。
