Zookeeper error: Cannot open channel to X at election address

Question

I have installed zookeeper in 3 different aws servers. The following is the configuration in all the servers

tickTime=2000
initLimit=10
syncLimit=5
dataDir=/         


        

Answer 1

Here is some ansible jinja2 template info for automating the build of a cluster with the 0.0.0.0 hostname in zoo.cfg

{% for url in zookeeper_hosts_list %}
  {%- set url_host = url.split(':')[0] -%}
  {%- if url_host == ansible_fqdn or url_host in     ansible_all_ipv4_addresses -%}
server.{{loop.index0}}=0.0.0.0:2888:3888
{% else %}
server.{{loop.index0}}={{url_host}}:2888:3888
{% endif %}
{% endfor %}
