[jira] [Commented] (CASSANDRA-9748) Can't see other nodes when
using multiple network interfaces
[ https://issues.apache.org/jira/browse/CASSANDRA-9748?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14736009#comment-14736009 ]
Jonathan Ellis commented on CASSANDRA-9748:
-------------------------------------------
Can you reproduce with 2.1 or 2.2?
> Can't see other nodes when using multiple network interfaces
> ------------------------------------------------------------
>
> Key: CASSANDRA-9748
> URL: https://issues.apache.org/jira/browse/CASSANDRA-9748
> Project: Cassandra
> Issue Type: Bug
> Environment: Cassandra 2.0.16; multi-DC configuration
> Reporter: Roman Bielik
>
> The idea is to setup a multi-DC environment across 2 different networks based on the following configuration recommendations:
> http://docs.datastax.com/en/cassandra/2.0/cassandra/configuration/configMultiNetworks.html
> Each node has 2 network interfaces. One used as a private network (DC1: 10.0.1.x and DC2: 10.0.2.x). The second one a "public" network where all nodes can see each other (this one has a higher latency).
> Using the following settings in cassandra.yaml:
> *seeds:* public IP (same as used in broadcast_address)
> *listen_address:* private IP
> *broadcast_address:* public IP
> *rpc_address:* 0.0.0.0
> *endpoint_snitch:* GossipingPropertyFileSnitch
> _(tried different combinations with no luck)_
> No firewall and no SSL/encryption used.
> The problem is that nodes do not see each other (a gossip problem I guess). The nodetool ring/status shows only the local node but not the other ones (even from the same DC).
> When I set listen_address to public IP, then everything works fine, but that is not the required configuration.
> _Note: Not using EC2 cloud!_
> netstat -anp | grep -E "(7199|9160|9042|7000)"
