# Getting started - Managing hdinsight using Azure Python SDK
12+
13+
These code samples will show you how to manage hdinsight using Azure SDK for Python.
14+
15+
## Features
16+
17+
This project framework provides examples for the following services:
18+
19+
### hdinsight
20+
* [] Using the Azure SDK for Python - hdinsight Management Library [azure-mgmt-hdinsight](https://pypi.org/project/azure-mgmt-hdinsight/) for the [hdinsight API](https://docs.microsoft.com/en-us/rest/api/hdinsight/)
21+
22+
## Getting Started
23+
24+
### Prerequisites
25+
26+
1. Before we run the samples, we need to make sure we have setup the credentials. Follow the instructions in [register a new application using Azure portal](https://docs.microsoft.com/en-us/azure/active-directory/develop/howto-create-service-principal-portal) to obtain `subscription id`,`client id`,`client secret`, and `application id`
27+
28+
2. Store your credentials an environment variables.
29+
For example, in Linux-based OS, you can do
30+
```bash
31+
export AZURE_TENANT_ID="xxx"
32+
export AZURE_CLIENT_ID="xxx"
33+
export AZURE_CLIENT_SECRET="xxx"
34+
export SUBSCRIPTION_ID="xxx"
35+
```
36+
37+
### Installation
38+
39+
1. If you don't already have it, [install Python](https://www.python.org/downloads/).
40+
41+
This sample (and the SDK) is compatible with Python 2.7, 3.3, 3.4, 3.5 and 3.6.
42+
43+
2. General recommendation for Python development is to use a Virtual Environment.
44+
For more information, see https://docs.python.org/3/tutorial/venv.html
45+
46+
Install and initialize the virtual environment with the "venv" module on Python 3 (you must install [virtualenv](https://pypi.python.org/pypi/virtualenv) for Python 2.7):
47+
48+
```
49+
python -m venv mytestenv # Might be "python3" or "py -3.6" depending on your Python installation
50+
cd mytestenv
51+
source bin/activate # Linux shell (Bash, ZSH, etc.) only
52+
./scripts/activate # PowerShell only
53+
./scripts/activate.bat # Windows CMD only
54+
```
55+
56+
### Quickstart
57+
58+
1. Clone the repository.
59+
60+
```
61+
git clone https://github.com/Azure-Samples/azure-samples-python-management.git
62+
```
63+
64+
2. Install the dependencies using pip.
65+
66+
```
67+
cd azure-samples-python-management/samples/hdinsight
68+
pip install -r requirements.txt
69+
```
70+
71+
## Demo
72+
73+
A demo app is included to show how to use the project.
74+
75+
To run the complete demo, execute `python example.py`
76+
77+
To run each individual demo, point directly to the file. For example (i.e. not complete list):
78+
79+
1. `python manage_ServiceName.py`
80+
81+
If the script starts with `disable_***.py`, it means that it is unavailable now.
82+
83+
The sample files do not have dependency each other and each file represents an individual end-to-end scenario. Please look at the sample that contains the scenario you are interested in
