set_fact: kafka_zookeeper_connection_string= wrong string

[noizo]

Hi. Thanks for perfect role, like it a lot, however:

This is my playbook:

- hosts: kafka
  vars:
    zookeeper_hosts: 172.31.32.93
    kafka_zookeeper_hosts:
      - 172.31.32.93
    kafka_hosts:
      - 172.31.46.135
      - 172.31.47.248
  roles:
    - {role: ansible_kafka ,kafka_hosts: "{{ groups.kafka | list }}", kafka_zookeeper_hosts: "{{ zookeeper_hosts | list }}", kafka_version: "0.11.0.2", kafka_scala_serverion: "2.10" }

There is a line in kafka-cfg.yml which suppose to create zookeeper connection string.
set_fact: kafka_zookeeper_connection_string="{{ kafka_zookeeper_hosts | join(':' ~ kafka_zookeeper_port ~ ',') }}:{{ kafka_zookeeper_port }}"

Instead of creating string like 172.31.32.93:2181 it creates something like
1:2181,7:2181,2:2181,.:2181,3:2181,1:2181,.:2181,3:2181,2:2181,.:2181,9:2181,3:2181

Could You please suggest a fix?

Hi @noizo,

Can you share the kafka_zookeeper_hosts value being used?

It can be printed out by adding a debug task right before the set_fact task.
