Yes, this does not seem unusual - the NMs will try to connect to the old RM for some time before they fail over to the new RM. If this time exceeds the heartbeat interval, the NMs may show up as disconnected until they reach out to the new RM. ~ Hariharan On Sun, Feb 25, 2024 at 4:12 PM Dong Ye <yedong...@gmail.com> wrote: > Hi, All: > > I have a question, in the high availability resource manager > scenario, how does the states of NodeManagers change if a new leader RM is > elected?
