riak won't start after changing nodename - linux

Question

I've just installed riak on my virtual machine (Ubuntu 14.04).
The problem is that when I've edited /etc/riak/riak.conf from:
nodename = riak#127.0.0.1
to
nodename = riak#10.20.0.110
which is ip of my virtual machine, service won't start. I got following error.
root#ubuntu-amd64:/home/ubuntu# riak console
config is OK

I've noticed that nodename variable is very sensitive, it won't work even with such configuration:
nodename = riak#localhost
Of course I've changed
listener.http.internal = 10.20.0.110:8098
listener.protobuf.internal = 10.20.0.110:8087
as well.

I found solution in this post.
sudo rm -rf /var/lib/riak/ring/* # delete the riak ring
