cannot set priority of namenode process

无法设置namenode进程的优先级可能是由于权限不足或进程不存在导致的。您可以尝试以下步骤解决此问题:
1. 确保您具有足够的权限来更改进程的优先级。您可以使用sudo命令以root用户身份运行命令。
2. 确认namenode进程正在运行。您可以使用ps命令检查进程是否存在。
3. 如果进程存在,请尝试使用renice命令更改进程的优先级。例如,要将进程ID为1234的进程的优先级设置为10,请使用以下命令:
```shell
sudo renice 10 1234
```
如果您不知道进程的ID,请使用以下命令查找进程:
```shell
ps aux | grep namenode
```
然后使用renice命令更改进程的优先级。
4. 如果您仍然无法更改进程的优先级,请检查系统日志以获取更多信息。您可以使用以下命令查看系统日志:
```shell
tail /var/log/syslog
```

ERROR: Cannot set priority of namenode process
This error usually occurs when attempting to set the priority of the Namenode process using the 'renice' command and the user running the command does not have sufficient privileges to do so.
To resolve this issue, try running the command with root privileges by adding 'sudo' before the command. For example:
```
sudo renice -n <priority> -p <process_id>
```
Replace `<priority>` with the desired priority level and `<process_id>` with the process ID of the Namenode process.
