comment topology file about ipv6 configuration
----------------------------------------------
Key: CASSANDRA-2329
URL: https://issues.apache.org/jira/browse/CASSANDRA-2329
Project: Cassandra
Issue Type: Improvement
Components: Core
Affects Versions: 0.7.3
Environment: all
Reporter: Eric Tamme
Priority: Trivial
Fix For: 0.7.4
There is little documentation regarding ipv6 working with cassandra. For the
cassandra propertyfilesnitch to work with ipv6, the ipv6 addresses must have
the colons escaped due to the parsing characteristics of
java.util.Properties.load().
Adding this documentation to the cassandra-topology.properties file would be
nice so that people dont have to hunt through source code and java doc to
figure out how to configure topology.
Here is a simple patch that will alert users to how to config topology for ipv6
use.

> # Native IPv6 is supported, however you must escape the : in the IPv6 Address
> # Also be sure to comment out JVM_OPTS="$JVM_OPTS
> -Djava.net.preferIPv4Stack=true"
> # in cassandra-env.sh
