http_proxy - setting up

If you are using http_proxy then you have to do on all nodes (including the controller):

Redhat/Centos

EDIT /etc/bashrc
# add as the last line:
export http_proxy=http://proxy_address:proxy_port
# change the proxy_address and proxy_port to what you use.
Save and exit

You may also have to setup so that http_proxy correctly handles localhost/127.0.0.1 , or make sure that localhost/127.0.0.1 calls do not use http_proxy.

Ubuntu/Debian

EDIT /etc/profile
# add as the last line:
export http_proxy=http://proxy_address:proxy_port
# change the proxy_address and proxy_port to what you use.
Save and exit

 You may also have to setup so that http_proxy correctly handles localhost/127.0.0.1 , or make sure that localhost/127.0.0.1 calls do not use http_proxy.

Verify it works

ssh node_address  #node_address is the address of a node part of the cluster
env |grep http_proxy
# if you then see something like (depending on what you set it to), then the change was successful:
http_proxy=http://proxy_address:proxy_port
