Hello !

Ansible has a variable "{{ playbook_dir }}" that gives the playbook directory path. What I understand is, while running the Ansible play, the sources related to Ansible playbook are copied to a temporary location for example:
/root/.ansible/tmp/ansible-tmp-1532003188.07-226176824704061/ and it is run from there. So, currently, for one of my method where I need to read a file, I need to pass "{{ playbook_dir }}" as a parameter while running the play, source code: https://gist.github.com/anis016/1c0a54a9fea7283ece474d0727ddb879#file-hive-py-L350 (Also, please check the play.yml below).
Is there any other way from where I can get the Playbook directory path directly and can use in my python source code without passing as a separate option?

play.yml

---
- name: hive playbook
  hosts: yum_hosts
  tasks:
  - name: Install yum requirements
    become: yes
    raw: yum install -y gcc openssl-devel python-devel libffi libffi-devel cyrus-sasl-devel

  - name: Install hive and kerberos modules
    become: yes
    pip:
      name: "{{ item }}"
      extra_args: --trusted-host files.pythonhosted.org --trusted-host pypi.org --trusted-host pypi.python.org
    with_items:
      - thrift_sasl==0.2.1
      - impyla

  - name: execute a DDL statement from a HQL file.
    hive:
      operation: file
      parameters: "--outputformat=csv2 --showHeader=false -f sample.hql --hivevar environment=default"
      playbook_path: "{{ playbook_dir }}"
      quorum: "sandbox.hortonworks.com:2181"
    register: result_execute

  - name: dump
    debug:
      msg: '{{ result_execute }}'
