Hi, I'm trying to setup a Cluster of apache Cassandra version 4.0.1 with 2 nodes:
1. on node1 (192.168.1.1), extracted tar.gz and config these on yml: - seeds: "192.168.1.1" listen_address: 192.168.1.1 rpc_address: 192.168.1.1 2. started node1 and a few seconds later it is UN 3.on node2 (192.168.1.2), extracted tar.gz and config these on yml: - seeds: "192.168.1.1" listen_address: 192.168.1.2 rpc_address: 192.168.1.2 4. started node2 but a few seconds later an error reported in system.log: INFO [ScheduledTasks:1] 2022-01-31 13:46:37,499 MessagingMetrics.java:206 - ECHO_REQ messages were dropped in last 5000 ms: 0 internal and 5 cross node.
