Hi Uwe, At first look, your configuration seems correct, see my comments below.

Indeed, you should have observed a communication between the source cluster and the target zookeeper. Do you see any errors in the log of the source cluster ? Or a log message such as:
"Unable to instantiate the log reader for target collection ..."
10. Enter some test data into the SOURCE 11. Explicit commit in SOURCE http://SOURCE:s_port/solr/scoll/update?commit=true&opensearcher=true !! (at least now there should be some traffic, or?)
Replication should start even if no commit has been sent to the source cluster.
12. Check errors and queues http://SOURCE:s_port/solr/scoll_shard1_replica1/cdcr?action=queues&wt=json{"responseHeader":{"status":0,"QTime":0},"queues":[],"tlogTotalSize":135,"tlogTotalCount":1,"updateLogSynchronizer":"stopped"}http://SOURCE:s_port/solr/scoll_shard1_replica1/cdcr?action=errors&wt=json{"responseHeader":{"status":0,"QTime":0},"errors":[]}! Why is the element queues is empty
The empty queue seems to indicate there is an issue, and that cdcr was unable to instantiate the replicator for the target cluster. Just to be sure, your source cluster has 4 shards, but not replica ? If it has replicas, can you ensure that you execute these command on the shard leader.
Kind Regards -- Renaud Delbru
