k8s No Route to Host from xxx to xxx failed on socket timeout exception

背景：从dlink 发布 flink on yarn 任务失败，报：No Route to Host from xxx to xxx failed on socket timeout exception ，但两个pod 相互ping的通，并且通过脚本/opt/flink/bin/flink run -m yarn-cluster -ynm V2xRTDataPersistenceToHDFS -s hdfs://hdfs-namenode-service:9000/flink-savepoints/savepoint-dbbfa8-06ca8afc6a59 -c xxx /opt/v2x-1.0-SNAPSHOT.jar发布的任务却是成功执行的？


解决：yarn pod 都删除待其恢复重启，成功发布。。。 奇怪的问题
