我在纱线模式下有一个火花簇，我直接在主节点上安装了Spring Cloud Data Flow，按照文档的简单步骤，一切顺利。
我创建了简单的流和任务，部署它们，没有发生任何事情
stream create ticktock --definition “time | log” --deploy
task create --name pi --definition "spark-yarn --spark.app-jar=<spark-example.jar> --spark.assembly-jar=<spark-assembly-jar-in-hdfs> --spark.app-class=org.apache.spark.examples.SparkPi"
在webUI中，我可以看到流已部署且任务处于未知状态。但是在纱线服务器的控制台中，出现了异常打印的内容如下：

我认为这意味着流和任务未成功部署，对吧？如何解决这个问题呢？感谢。
