我正在尝试构建一个3节点群集（2个namenode（nn1，nn2）和1个datanode（dn1））。使用namenode webui，我可以查看nn1是活动的，nn2是备用的。但是，当我杀死活动的nn1时，备用nn2将不处于活动状态。请帮助我我做错了什么或者需要修改什么
nn1/etc/主机

127.0.0.1 localhost
192.168.10.153 nn1
192.168.10.154 dn1
192.168.10.155 nn2

nn2/etc/主机

127.0.0.1       localhost nn2
127.0.1.1       ubuntu

    # The following lines are desirable for IPv6 capable hosts
    ::1     ip6-localhost ip6-loopback
    fe00::0 ip6-localnet
    ff00::0 ip6-mcastprefix
    ff02::1 ip6-allnodes
