ERROR: Cannot set priority of namenode process

This error message usually indicates that the user does not have sufficient privileges to change the priority of the namenode process. To resolve this issue, you can try running the command with elevated privileges, such as using the "sudo" command or logging in as the root user. Alternatively, you can check if there are any restrictions in place that prevent the user from changing process priorities. You may also want to check the system logs for any related error messages or consult your system administrator for further assistance.

hadoop102: ERROR: Cannot set priority of namenode process 15847

这个错误是因为在启动Hadoop namenode过程中，系统无法设置进程优先级。这通常是由于缺少root权限或者系统限制导致的。

为了解决这个问题，你可以尝试以下几种方法：

1. 以root用户身份启动Hadoop namenode。
2. 检查系统内核参数是否允许设置进程优先级。你可以使用sysctl命令检查或修改内核参数。例如，可以使用以下命令检查相关参数：

   sysctl -a | grep prio

如果相关参数的值为0，则表示系统禁止设置进程优先级。你可以修改相关内核参数的值，使其允许设置进程优先级。具体的修改方法可以参考相关文档。

希望这些方法可以帮助你解决问题。
