Enhanced IP resolution for machines with multiple network interfaces
---------------------------------------------------------------------
Key: CASSANDRA-3211
URL: https://issues.apache.org/jira/browse/CASSANDRA-3211
Project: Cassandra
Issue Type: Improvement
Components: Hadoop
Affects Versions: 0.8.5
Environment: Mac OS X and Linux with machines that have multiple
network interfaces whereby the IP associated with the split is not on the
network interface associated with localhost.
Reporter: Brian ONeill
Fix For: 0.8.6
On unix machines that have multiple network interfaces whereby the IP
associated with the split is not on the network interface associated with
localhost, the getLocation method cannot find the proper IP and throws an
exception "no connection available".
I changed the implementation to use NetworkInterface instead of InetAddress
using getLocalHost().
This is more reliable. See the following references:
