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 {color:#FF0000}NS1 {color}process exits, setting the states of safemode, {color:#FF0000}NS2{color}, {color:#FF0000}NS3{color}, and {color:#FF0000}NS4 {color}fails. Similarly, when the {color:#FF0000}NS2{color} process exits, only the safemode state of {color:#FF0000}NS1{color} can be set successfully. When the {color:#FF0000}NS1{color} process exits: Before the change: !image-2022-03-15-09-29-36-538.png|width=1145,height=97!
