hi, we create by mistake worker node ( worker11 with datanode & namenode ) , while cluster already have worker11 only when we start the new worker11 we notice that other node - worker11 already exsist so the problem is that we erased the OS of worker11 ( without delete it from the cluster ) , and new worker - worker11 stay in the cluster after couple hour we notice that heartbeat loses on the new worker11 and after some time worker11 crash , so we need to start this machine ( boot ) again and so on it is clear that all the problem on worker11 are because this is duplicate machine , ( while the old worker11 machine was removed from the VM center ( OS ) so what is the workaround to do on worker11 node ? , in ordeer amabri cluster will get this machine without problems?
