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.
Change termination protection
When you're all done, don't forget to terminate the instances in your cluster, otherwise you will continue to be billed for them! To terminate the instances, you'll first need to select the Change Termination Protection option in the Actions menu, shown here.
