Hi Team,

We are doing the 10 hosts customized installation in that 3 CZ and 1 Management Server.

Management server is getting the connection timeout error for 7199 port when doing the installation. we have checked the firewall matrix and all ports are listening well. we are not able to find any clues.

Note: 7199 is listening on 0.0.0.0 in Cassandra node.

Ashok, From Management server node do the following to each of the cassandra nodes.

telnet cass_ip 7199

You should be able to connect on this port. If not, then you know where the problem is.

its open and we can do the telnet, but we can’t make it from nodetool

4

Our infrastructure is based on multiple network interface with restrictions so if the Cassandra is bind with 0.0.0.0 we can’t able to reach from neighbour server. We mimic this and update the default.sh to add this line -Djava.rmi.server.hostname=IP and restart now after these changes I can able to connect.

Currently -Djava.rmi.server.hostname= has to be updated on /conf/cassandra-env.sh file, but this will be overwritten on cassandra service restart.

To make this change persistent after restart, update cassandra-env.sh file under /source/conf/cassandra-env.sh
