need to install "jmespath" prior to running json_query filter

[sangdrax8]

I am using Ubuntu 16LTS, and attempting to install a plugin with the ansible playbook results in an error about a missing python package.

TASK [ansible-elasticsearch : set_fact] ****************************************************************************************************** fatal: [**********]: FAILED! => {"failed": true, "msg": "You need to install \"jmespath\" prior to running json_query filter"}

After installing python-jmespath on my local machine (where I run ansible) everything works.
apt-get install python-jmespath

I don't know if there is a way to ensure this is installed, or simply documentation stating required python packages that are above and beyond what is required to run ansible.

I have just come across this same issue on Ubuntu 16.04 LTS. I noticed that if the variable 'es_plugins_reinstall' is set to true, 'es_plugins_reinstall: true' then Ansible runs without any problem (I am not saying this is a solution).

es_plugins_reinstall - defaults to false. If true, all currently installed plugins will be removed from a node. Listed plugins will then be re-installed.

We do indeed install this as a dependency for our tests e.g. https://github.com/elastic/ansible-elasticsearch/blob/master/.kitchen.yml#L31 as the tests run locally.

I think a comment in our README this is needed locally is probably sufficient. I added a note under #362

The actual issue likely has to do with the 'Ansible' package (eg. RPM) itself. In Amazon Linux1 the EPEL version of the RPM has a hard dependency for Python 2.6. But if you update your system, Python 2.7 will get installed. So while /usr/bin/python -> /etc/alternatives/python -> python27, /usr/bin/python2 likely still points to python2.6. Therefore you have to install the 2.6 version of the 'jmespath' module.

Alternatively fix /usr/bin/python2 to point to 2.7. Which begs the question, why is Ansible apparently invoking 'python2' instead of just 'python'?

on RHEL we can use yum install python3-jmespath
