cannot overwrite file /home/uisrc/.config/qtproject/qtcreator/qtversion.xml: permission denied

这个错误提示是因为你没有足够的权限来覆盖/home/uisrc/.config/qtproject/qtcreator/qtversion.xml文件。你需要以管理员身份运行命令或者使用sudo命令来获得足够的权限。可以尝试使用以下命令：

sudo cp /path/to/your/file /home/uisrc/.config/qtproject/qtcreator/qtversion.xml

其中，/path/to/your/file是你要复制的文件的路径。请确保你有足够的权限来执行该命令。

copyFromLocal: Cannot create file/user/hyf/text.txt._COPYING_. Name node is in safe mode.

This error message is indicating that the Hadoop NameNode is currently in safe mode, which means that it is performing maintenance tasks or recovering from a failure. While the NameNode is in safe mode, it is not possible to create new files or modify existing ones.

To resolve this issue, you will need to wait until the NameNode exits safe mode. Once the maintenance tasks are complete, you should be able to create the file or copy it to HDFS using the copyFromLocal command. Alternatively, you can use the -force flag with the copyFromLocal command to overwrite the file in HDFS if it already exists. However, this is not recommended as it may result in data loss or corruption.

cp: overwrite '/home/linux_7210764132/apache-tomcat-8.5.96/webapps/ROOT/WEB-INF/classes/AddStudent.class'?

这是一个cp命令的提示信息，询问是否覆盖目标文件。cp命令用于将一个文件或多个文件复制到另一个目录中。在这个例子中，cp命令试图复制一个名为AddStudent.class的文件到目录/home/linux_7210764132/apache-tomcat-8.5.96/webapps/ROOT/WEB-INF/classes/中。如果该目录中已经存在一个名为AddStudent.class的文件，则会出现提示信息，询问是否覆盖该文件。如果您想覆盖该文件，请输入y或yes。如果您不想覆盖该文件，请输入n或no。
