  • Welcome to your cluster

    Upon successful login, you should see a welcome screen and be presented with a command prompt.  The message telling you how to gain access to the Hadoop "UI" should be taken with a grain of salt, however, as that user interface is presented in Lynx, a text-based Web browser.

  • The bin folder

    Switch to the bin folder (using the "cd bin" command) and list its contents (using the "ls" command).  You will see that Hadoop, HBase, Hive and Pig are all neatly installed for you.

    They're ready to run, too.  To check this out, enter the "hive" command, and you'll be placed at Hive's command  line prompt.

  • HBase prompt and "grunt"

    Use the "hbase shell" command to get to the HBase prompt or use the "pig" command to get to the Pig prompt (called "grunt").

    Although not shown here, you can also use the "hadoop fs" command to perform Hadoop Distributed File System (HDFS) operations and, of course, the "hadoop jar" command to run a Hadoop MapReduce job.
