Setting safemode should not be interrupted by abnormal nodes. For example, we have four namenodes configured in the following order: NS1 -> active NS2 -> standby NS3 -> observer NS4 -> observer. When the `NS1` process exits, setting the states of safemode, `NS2`, `NS3`, and `NS4` fails. Similarly, when the `NS2` process exits, only the safemode state of `NS1` can be set successfully. When the `NS1` process exits: Before the change: ![image](https://user-images.githubusercontent.com/55134131/158288412-b0915dba-aa69-4e71-a47d-1d7728ba673d.png) After the change: ![image](https://user-images.githubusercontent.com/55134131/158288423-f7de2689-ad0b-455e-9717-1b5ff877f20f.png) -- This is an automated message from the Apache Git Service.
