Riak admin services shows blank list

[azowarg]

Hello, I came to this repo from this issue.
I just wanted to let you know that for some reason in the nhs 3.2.2 version, the command riak admin services shows in the output blank list.

root@riak-0:/var/lib/riak# riak admin services
[]

But I am sure that the service works without problem and for example I can check for it with another command.

root@riak-0:/var/lib/riak# riak admin wait-for-service riak_kv
riak_kv is up

Apologies, this got missed by me and forgotten about.

I can confirm the issue:

% riak admin services
[]
% riak rpc riak_core_node_watcher services
[riak_kv, riak_pipe, riak_repl]

There is a workaround to use the second command (which is what the admin script is doing behind the scenes):

So why the admin script doesn't work directly .... I don't know.

@hmmr - you've fixed problems like this before, do you know?

services)
        if [ $# -ne 1 ]; then
            echo "Usage: $SCRIPT $1"
            echo ""
            echo "Lists the services available on the node. See also: wait-for-service"
            exit 1
        fi
        
        SERVICES=`"${PLATFORM_BIN_DIR}/riak" rpc riak_core_node_watcher services || :`
        echo $SERVICES
        ;;

This works - but why is this necessary?

I assume I'm missing something obvious.

There appears to be an issue with passing arguments to rpc, to deal with which there was an alternative version of rpc: https://github.com/OpenRiak/riak/blob/nhse-develop/rel/files/lib.sh#L28-L32.

All in all, replacing rpc with rpc_raw in the call to rpc riak_core_node_watcher services should be sufficient.

Here's a PR: #11 for that.
