Conventions

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "Optionally, make sure to disable NetworkManager in your CentOS boxes."

A block of code is set as follows:

# nano worker_template_pp.json
{
 " name": "PP-Worker-Template",
  "flavor_id": "2",
  "plugin_name": "vanilla",
  "hadoop_version": "2.7.1",
  "node_processes": ["nodemanager", "datanode"],
  "auto_security_group": true
}

Any command-line input or output is written as follows:

# export IMAGE_ID=49fa54c0-18c0-4292-aa61-fa1a56dbfd24
# sahara image-register --id $IMAGE_ID --username centos 
--description 'Sahara image CentOS 7 Hadoop Vanilla 2.7.1'

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "The first window in the wizard exposes the Plugin name and its version."

Note
