Eclipse Oxygen (4.7.1) （eclipse-jee-oxygen-1-win32-x86_64.zip）

Installing Cygwin

After installing the prerequisite software, the next step is to install the Cygwin environment. Cygwin is a set of Unix packages ported to Microsoft Windows. It is needed to run the scripts supplied with Hadoop because they are all written for the Unix platform.
