-yarnship 命令参数时，资源目录和 jar 文件会被添加到 classpath 中
路径貌似是: hdfs://user/hdfs/.flink/${appicationId}/，但是 ${appicationId} 是动态的,需要任务启动后才知道.
yarnship的作用是把你想要的文件放到集群每个node的classpath下.
Resources and JARs shipped via –yarnship will be ordered in the Classpath (Flink-13127)
When using the --yarnship command line option, resource directories and jar files will be added to the classpath in lexicographical order with resources directories appearing first.
当使用——yarnship命令
