I'm trying to set up the Cross Cluster Replication locally in a single node. I have been using one elasticsearch/kibana instance running as a service (version 7.9.3) with default settings and everything works fine. Now for the CCR I downloaded elasticsearch/kibana as tar.gz (version 7.10.0) and executed them with the following settings (I report only configurations different from the default one):
cluster.name: ClusterB http.port: 9201
server.port: 5602 elasticsearch.hosts: ["http://localhost:9201"]
When I execute elasticsearch from the /bin directory this error is thrown
[WARN ][o.e.d.HandshakingTransportAddressConnector] [giacomo-ondesca-1] handshake failed for [connectToRemoteMasterNode[127.0.0.1:9300]]
Also seems that kibana tries to connect to the other elasticsearch instance (the one running as a service on port 9200).
What I'm doing wrong?
