Note 1: Version 6 is CRITICAL! Although you can compile the tutorial code with Java 7, it WILL NOT RUN on Amazon Elastic MapReduce. While it's a little more work to setup, it's a better method for dealing with larger, more complicated projects.

But, that original tutorial used the web interface for Amazon Elastic MapReduce, while this new tutorial uses a command-line interface to Elastic MapReduce ( link 1, link 2). This tutorial is based on Steve Salevan's blog post MapReduce for the Masses: Zero to Hadoop in Five Minutes with Common Crawl. Other features include full ANSI/VT100 terminal emulation, break-sequence support (for Cisco, etc), a line-buffered send mode, a fully featured SSH/Telent client, and much more.See also: New tutorial (updated for Spring 2016) If you can't find an OS X driver for yourĪdapter (eg, Belkin), give Serial a try as it'll probably work! The free demo is fully functional for 7 days. Serial Serial is a great Terminal Emulation Program with built-in driver support for most USB to serial devices. Or, ctrl-click/right-click on the app and select Open from the pop-up menu so not to permanently lower your security settings.

If you can't find a driver for your adapter (eg, Belkin), try Serial which has built-in support for most (if not all) USB-Serial adapters. If you're looking for a command line app, there's Screen (built-in) or Minicom. The following Mac OS X GUI applications are available: Having installed the right driver for our USB-serial adapter, we also need to install some terminal emulation software before we can connect to anything.
