   > If there are no master can this work? We should select the leader from the 
whole cluster rather than select the leader from master, I didn't see any 
design related to this PR, you should provide the newly design doc related to

   Hi, this is an OSPP project. My mentor is @zhuxt2015. The design plan for 
the raft plugin has been discussed. The design link is [Add new registry plugin 
based on raft](https://github.com/apache/dolphinscheduler/issues/10874). 
According to the discussed plan, masters will form a raft cluster, and the 
leader will only be elected among the masters, just like in ZK. For the three 
master nodes, at least two must be alive to provide services normally.
