Why clusterstate.json says active for a killed Solr Node?
I want to get cluster state of my SolrCloud and this is my method:
private final CloudSolrServer solrServer;
public SolrCloudServerFactory(String zkHost) throws MalformedURLException {
this.solrServer = new CloudSolrServer(zkHost);
solrServer.connect();
}
and I get what I want from solrServer variable. However I killed a running
Solr node from my cluster and I see that clusterstate.json at still shows
it as active and my solrserver variable says same thing too. I have killed
that start.jar but why it is still active? How can I understand it is down?
I think that Solr admin page doesn't look at clusterstate.json?

Here is my code to check state of node:
!liveNodes.contains(replica.getNodeName()) ? ZkStateReader.DOWN :
replica.get(ZkStateReader.STATE_PROP).toString()

You currently kind of have to look at both if you want to know the true state.
An active state means that shard is up to date and online serving - as long as it's live node is also up.

Is it enough just look at only live nodes(if not: could you tell me is
there any example code part at Solr source code)? By the way what does
active means for clusterstate.json?

The true current state is the live nodes info combined with the
clusterstate.json. If a node is not live, whatever is in clusterstate.json
is simply it's last state, not the current one.
