Hive is quite easy to install. Simply grab the current hive release hive-<date>.tar.gz and unpack it somewhere. That will create one directory, hive. Inside it you will find a bunch of jar files, and two scripts: hive (for Unix) and HIVE.BAT (for Windows). Run the appropriate one, and Hive should pop up a window with three panels, and print some text to the console. You're running Hive! Easy, huh?
