Dear Mr. Shalin,
Yes. I mean "state" in Cluster State API and UI.
Let me explain what happened previous days by detail:
Think I have Collection A distributed across node1 (the leader), node2 and
node 3.
I used the following command to block node 1 solr and zookeeper ports from
being listend:

When you say it is active, I presume you mean the "state" as returned by
the Cluster Status API or as shown on the UI. But is it still the leader?
Are you sure the firewall rules are correct? Do you see disconnected or
session expiry exceptions in the leader logs?

Thanks Shalin. our "zkClientTimeout" is 3, so the leader should be
changed by now; However, the previous leader is still active.

When you block communication between Zookeeper and the leader, the ZK
client inside Solr will disconnect and its session will expire after the
session timeout. At this point a new leader should be elected
automatically. The default timeout is 30 seconds. You should be able to see
the value in solr.
The leader status is active. My main question is that how I can change the
leader in SolrCloud.

i don't understand your problem clearly but solr admin ui has some bugs.
to check your cloud nodes state use the CLUSTERSTATUS command:
/admin/collections?action=CLUSTERSTATUS
in some cases your command was done but you can't see in admin ui.

Thanks Shawn for the reply. when I try to add a document to solr I get the
"no route to host" exception. this means that SolrCloud is aware of the
blocking ports; However, zookeeper does not automatically change the leader!
