Dear all
I'm trying to interface a C application with a Riak cluster. To do this, I have set up a small two node cluster with Riak to which I'm already able to communicate with HTTP requests. My next step is trying to run the riak-c-client <https://github.com/basho-labs/riak-c-client> . However, there are some problems with certain functions. If I execute the following commands, the application never returns and gets stuck: ./riak_c_example --host hostname --port 8098 --server-info ./riak_c_example --host hostname --port 8098 --ping These commands get stuck on the 'err = riak_ping(cxn)' and the 'err = riak_serverinfo(cxn, &serverinfo_response)' lines. However, when I execute the following HTTP request, I get a perfect response: curl http://hostname:8098/stats curl http://hostname:8098/ping If I try to put a key in the database via the c application, I get segmentation faults. When executing the following command, I get a segmentation fault upon execution of the line 'riak_get_response_print(&print_state, get_response)'. ./riak_c_example --host hostname --port 8098 --put --key "testKey" --value "testValue" --bucket "testBucket" The versions of the software I use are: Riak 2.1.1 which runs on two CentOS 7 servers OS of riak_c_example: Scientific Linux CERN SLC 6.6 gcc: 4.8.2 and 4.4.7 (tried both) The configuration files all contain their default values, I only changed the hostnames and restricted the ports with the following two lines as to not have to open up the entire firewall: erlang.distribution.port_range.minimum = 6000 erlang.distribution.port_range.maximum = 7000 If needed, I can give more information on the configuration. Do you have any idea what might be the source of these problems and how to fix them? Thank you in advance Kind regards Tom Van Steenkiste
