riak_erlang_client issue with riak_pb extension

2015-08-04 Thread Humberto Rodriguez Avila 
 Hello, I have been working in a extension to riak_pb, but every time that I 
try to use my new message in my extension of riak_erlang_client I obtain this 
message "Socket error while sending riakc request: einval. Bad value on output 
port 'tcp_inet’".

 Any suggestion?

Thanks in advance,
Humberto

status of signature version 4 requests

2015-08-04 Thread Henrik Lund Kramshøj 
Hi There

I am researching self-hosted alternatives to S3, and found Riak CS.
Setup was OK, and I currently can access the server fine with s3cmd

Unfortunately I cannot make it work with AWS SDK PHP version 3, since it
uses signature version 4.

I have done lots of trial and error, using PHP
define('AWS_KEY', 'xxx');
define('AWS_SECRET_KEY', 'xxx');
$client = new S3Client([
'credentials' => [
'key'=> AWS_KEY,
'secret' => AWS_SECRET_KEY
],
'region' => 'local',
'version' => '2006-03-01',
'endpoint' => '172.xx.x.xx:8080',
//'signature_version' => 'v4'
]);

signature_version can only be v4 or anonymous.

What is the expectation with v4 requests?

I did find the option, auth_v4_enabled:
root@riaks2:/etc/riak-cs# cat advanced.config
[
 {riak_cs, [
%%{auth_v4_enabled, true}
  ]}
].

but it ends up in error 500
""Internal Server Error""

Do I need more configuration, or is it not ready.



root@riaks2:/etc/riak-cs# lsb_release -a

Re: is it possible to use FQDN instead of IP in riak.conf for "listener.http.$name” field?

Can confirm, we have this set in our production cluster.

Today I detached the network bond(we used the bond mode 6/0) in several
nodes of the riak cluster. After that, "ifconfig" command show decreased
"dropped" packages,
There're only 1~2 dropped network packages during the last four hours.

However, I want to know what's the status of the Riak cluster?
Currently I started riak-cs service on four new nodes. That's ok, they can
service.
how many hours those four node will take to leave the cluster?
