Install Cloudera client on Linux

Install Cloudera client on Linux and verify that the Cloudera CLI client is working.

To avoid conflicts with older versions of Python or other packages, Cloudera recommends that you install the Cloudera client in a virtual environment. Use the virtualenv tool to create a virtual environment and install the client.

Use pip to install the client on a virtual environment:

mkdir ~/cdpclienv

virtualenv ~/cdpclienv

source ~/cdpclienv/bin/activate

~/cdpclienv/bin/pip install cdpcli

To upgrade the Cloudera client to the latest version, run the following command:
```
~/cdpclienv/bin/pip install --upgrade cdpcli
```
After the client installation process is complete, run the following command to confirm that the Cloudera client is working:
- If virtualenv is activated: cdp --version
- If virtualenv is not activated: ~/cdpclienv/bin/cdp --version
