根据您提供的信息,启动Hadoop集群时出现了一些警告和错误。具体来说,警告信息指出您正在启动所有的Hadoop守护进程,这不是一种推荐的生产部署配置方式,并且建议您使用CTRL-C来中止启动过程。此外,错误信息提示您需要停止正在运行的某些Hadoop守护进程,包括namenode、datanode、secondarynamenode和nodemanager。
根据错误信息,您需要先停止正在运行的Hadoop守护进程,然后再重新启动它们。您可以使用以下命令来停止Hadoop守护进程:
```
$HADOOP_HOME/sbin/stop-all.sh
```
该命令将停止所有的Hadoop守护进程。在停止之后,您可以使用以下命令来启动Hadoop守护进程:
```
$HADOOP_HOME/sbin/start-all.sh
```
该命令将启动所有的Hadoop守护进程,包括NameNode、SecondaryNameNode和DataNode。在启动过程中,您可以使用以下命令来检查Hadoop守护进程的状态:
- `jps`:列出所有正在运行的Java进程。
- `hdfs dfsadmin -report`:列出HDFS的状态报告。
- `yarn node -list`:列出YARN节点的状态。
如果所有的Hadoop守护进程都成功启动,则您的Hadoop集群已经成功启动,可以开始使用了。

从你提供的信息来看,你已经成功启动了 Hadoop 的所有守护进程。Jps 命令显示你的 ResourceManager 和 NodeManager 守护进程已经在运行。可以使用 Hadoop 自带的 Web 界面(一般为 http://localhost:50070/)来检查 Hadoop 的状态和任务运行情况。
