plugin binary can't find elasticsearch defaults file on Ubuntu 14.04

[philipwigg]

I am using Ubuntu 14.04.

I am configuring Elasticsearch in a role like so:-

    - { role: elasticsearch,
              es_instance_name: "es01",
              es_heap_size: "3g",
              es_data_dirs: "/opt/app/elasticsearch/data",
              es_log_dir: "/opt/app/elasticsearch/logs",
              es_work_dir: "/opt/app/elasticsearch/temp",
              es_config: { network.host: '[ "_local_", "_docker0_" ]',
                           transport.host: '_eth0_',
                           http.port: 9200,
                           transport.tcp.port: 9300,
                           max-open-files: true,
                           bootstrap.mlockall: true,
                           script.inline: true,
                           script.indexed: true,
                           index.translog.durability: async,
                           index.queries.cache.everything: true } }

This leaves me with a defaults file at /etc/default/es01_elasticsearch.

This happens when I try to run the plugin command:-

root@my-es-host:/usr/share/elasticsearch# bin/plugin                                               │~
bin/plugin: 49: .: Can't open //etc/default/elasticsearch

I can fix it up manually by editing bin/plugin like so:-

ES_ENV_FILE="/etc/default/es01_elasticsearch"

Am I missing some configuration or is this a bug? Thanks for your help.

Hi @philipwigg, sorry for the delay and thanks for opening this issue.

Is there a reason you are manually installing the plugin instead of using something like the following in the playbook?

  vars:
    es_plugins:
        - plugin: license

I don't consider this a bug as /usr/share/elasticsearch will be used for all the nodes, in a multiple nodes per host setup and thus it's not possible to edit the bin/plugin script itself.
Also the role does allow installing plugins, which cover this ENV setting already.

Closing for now. Feel free to reopen if you disagree and want to discuss this further.
