Re: Does datastax java driver works with ipv6 address?

2015-11-05 Thread Eric Stevens 
The server is binding to the IPv4 "all addresses" reserved address
(0.0.0.0), but binding it as IPv4 over IPv6 (:::0.0.0.0), which does
not have the same meaning as the IPv6 all addresses reserved IP (being ::,
aka 0:0:0:0:0:0:0:0).

My guess is you have an IPv4 address of 0.0.0.0 in rpc_address, and the
server is binding as instructed.  Probably you just need to set rpc_address
to either :: or the node's actual IPv6 address.

As for IPv6 testing for Cassandra in general, it has been brought up, 
but little testing is done at this time. If you have some contributions 
to be made in this area, I'm sure they would be greatly appreciated. You 
are in a relatively unique position with an IPv6-only cluster, so your 
input is valuable.

Thanks Michael,

Actually I find the problem is with the sever setup, I put "rpc_address:
0.0.0.0" in the config, and I find the sever bind to the address like this:

tcp0  0 :::9160 :::*
 LISTEN  2411582/java
tcp0  0 :::0.0.0.0:9042 :::*
 LISTEN  2411582/java

So using the sever ip "2401:db00:11:60ed:face:0:31:0", I can connect to the
thrift port 9160, but not the native port 9042. Do you know the reason for
this?

Thanks
Dikang.

Does datastax java driver works with ipv6 address?

2015-11-04 Thread Dikang Gu 
Hi there,

I have ipv6 only cassandra cluster, and I'm trying to connect to it using
java driver, like:

Inet6Address inet6 = (Inet6Address)
InetAddress.getByName("2401:db00:0011:60ed:face::0031:");
cluster = Cluster.builder().addContactPointsWithPorts(Arrays.asList(new
InetSocketAddress(inet6, 9042))).build();
session = cluster.connect(CASSANDRA_KEYSPACE);

But it failed to connect to the cassandra, looks like the java driver does
not parse the ipv6 address correctly, exceptions are:
