Hi ,

I’m trying to create folders in loop under HDFS file system - From some reason, I can not run it in loop

The playbook needs to run 2 commands

1. hadoop fs -mkdir folder1
2. hadoop fs -mkdir folder2

**Try #1 -**

```auto
- hosts: gw
  become: true
  become_user: hdfs
  vars:
    folders:
        - /folder1
        - /folder2

  tasks:

```

```auto

```

I would say you could derive it from the docs, but this should work:

- name: create Main HDFS folders  
&nbsp;&nbsp;shell: "hadoop fs -mkdir {{ item }}"  
&nbsp;&nbsp;with\_items: "{{ folders }}"
