What are you autocommit settings? The documents should be forwarded to
each replica from the leader during ingestion. However, they are not
visible on the follower until a hard commit(openSearcher=true) or soft

Restarting the node cleared out the problem and everything recovered.
Thanks!

Scheduling is currently outside of the scope of Solr and SolrCloud.

Ya :-) I need it for different reason.
I have 8 server nodes and one of them has to invoke scheduled data import
(by invoking CloudSolrServer)... And that's why I need to identify exclusive

solution). I don't want to invoke schedu
Since SolrCloud is a master-free architecture, you can send both queries
and updates to ANY node and SolrCloud will assure that the data gets to
where it belongs
its way faster to send them to right node
Why do you think you need to know which node is "the leader"? Answer: You
don't - SolrClound is NOT a master/slave architecture; there is no "master"
node.
Each shard has its own "leader", which can vary over time. It's called
"leader election". But, there is no cosmic significance to being a
Replica asks to Zookeper and Leader does not do anything. Thanks for your
answer Otis.

Hi Otis;
You said:
"It can just do it because it knows where things are."
Does it learn it from Zookeeper?

If query comes to shard X on some node and this shard X is NOT a
leader, but HAS data, it will just execute the query. If it needs to
query shards on other nodes, it will have the info about which shards
to query and will just do that and aggregate the results. It doesn't

Leaders don't have much to do with querying - the node that you query will
determine what other nodes it has to query to search the whole index and do a

I believe it indexes locally on leader first. Otherwise one could end
up with a situation where indexing to replica(s) succeeds and indexing
to leader fails, which I suspect might create a mess.
