I installed the 32-bit version of the Datastax Community edition and after that all sorts of strange things started happening.
Turns out that during the install, it hijacked my Java and Python installs and redirected them to its own private versions, contaminated my JAVA_HOME and PYTHONPATH (referring them to its private installs of Java and Python) and prepended itself to the system PATH.
The PATH thing I can ALMOST forgive, as there are a gazillion other software packages that do the same and it has become an irritating modus operandi. What I DO object to, however, is hijacking my Python (version 3.x, instead of 2.whatever the Datastax CE uses) and Java installations (WTF is the point in keeping my Java up to date, allowing its stupid updater to run and pester me continuously when suddenly somebody comes along and voids all that "effort"?). Politely put, this is BS. The installer, of course, did not ASK nor WARN me of this. All that it was concerned about was, if I wanted to start the Datastax services on boot.
A similar topic was already at http://www.datastax.com/support-forums/topic/datastax-community-windows-installer-eclipse
Now, to end this rant in a constructive way: Is there a way to kindly request (or force) the Datastax CE (or its installer) to not contaminate my (development) system with its "business" or is the only workaround to install it in a separate (or virtual) machine which it can keep all for itself?
