Summary: Cannot contact other nodes on Windows 7 ccm Key: CASSANDRA-11073 URL: https://issues.apache.org/jira/browse/CASSANDRA-11073 Project: Cassandra Issue Type: Bug Components: Streaming and Messaging Environment: windows 7 Reporter: Paulo Motta Assignee: Paulo Motta Priority: Minor Before CASSANDRA-9309 was fixed the {{OutboundTcpConnectionPool}} did not bind the client socket to a specific ip/port, so the Windows kernel always picked {{127.0.0.1:random_port}} as client socket address for ccm nodes, regardless of the {{listen_address}} value. After fixing CASSANDRA-9309 the {{OutboundTcpConnectionPool}} now binds outgoing client sockets to {{listen_address:random_port}}. So any ccm cluster with more than one node will bind client sockets to {{127.0.0.n}} where n is the node id. However, the nodes cannot contact each other because connections remain in the {{SYN_SENT}} state on Windows 7, as shown by netstats: {noformat} TCP 127.0.0.2:50908 127.0.0.1:7000 SYN_SENT {noformat} This bug is preventing the execution of dtests on Windows 7, and was also experienced by [~Stefania]. I suspect its a configuration/environment problem, but firewall and group policies are disabled. The funny thing is that it does not happen on cassci, but afaik there are no Windows 7 nodes there Commenting [this line|https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/net/OutboundTcpConnectionPool.java#L139] fixes the issue, but it's definitely not a solution. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
