Subject Re: Documentation on installing Hadoop 2.2.0 on Microsoft Windows
Date Thu, 24 Oct 2013 13:27:32 GMT
No Cygwin is involved...We have the installation via MSI clearly documented
on our site. Python, Visual C++, JDK and .Net framework. This work was done
in conjunction with Microsoft who is not in the business of supporting
Cygwin. Hadoop is Java and Java runs on windows.
