Description

show cluster return with msg: 500 null

 

reproduction:

1. start 3C3D cluster successfully
2. execute stop-confignode.sh and stop-datanode.sh on the other 2 nodes(not the leader)
3. start-cli.sh -h <leader IP>
4. show cluster

说明：

一般来讲，3节点集群，挂掉2个节点就是不可用的。

所以这个情况并非不可接受，但是希望将错误提前，比如：在连接时就拒绝连接。
