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: " The URL for NameNode is http://<namenode_host>:<port>/ and the default HTTP port is 50070."

A block of code is set as follows:

    <property>  
     <name>io.file.buffer.size</name> 
     <value>4096</value>  
     <description>read and write buffer size of files</description>
    </property>

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

${path_to_your_input_dir}
${path_to_your_output_dir_old}

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: "Under the Tools section, you can find the YARN configuration file details, scheduling information, container configurations, local logs of the jobs, and a lot of other information on the cluster."
