All of the points you bring up are valid, and we have plans to have the installer address them in the future.</p> <p>Regarding a workaround, unfortunately there is no way to prevent the installer from modifying those environment variables. You shoud however, be able to revert the changes made there, and still have OpsCenter work, if a few modifications are made to the opscenter start up scripts. We will verify what changes need to be made and that everything works correctly in that situation and get back to you soon.</p> <p>-Nick </p> http://www.datastax.com/support-forums/topic/datastax-windows-install-hijacks-java-and-python#post-4380 Tue, 31 Jul 2012 06:15:01 +0000 marek 4380@http://www.datastax.com/support-forums/ <p>Hi!</p> <p>I installed the 32-bit version of the Datastax Community edition and after that all sorts of strange things started happening.</p> <p>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.<br /> 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.</p> <p>A similar topic was already at <a href="http://www.datastax.com/support-forums/topic/datastax-community-windows-installer-eclipse" rel="nofollow">http://www.datastax.com/support-forums/topic/datastax-community-windows-installer-eclipse</a></p> <p>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? </p> http://www.datastax.com/support-forums/topic/datastax-community-windows-installer-eclipse#post-2057 Thu, 07 Jun 2012 08:49:18 +0000 Anonymous 2057@http://www.datastax.com/support-forums/ <p>Hello,<br /> I had the same problem. I have installed java 6 and java 7 on a 64 bit windows. It worked with the x86 java 6 version, but it still gave the same error when I tried with the 64 bit java 7 version.<br /> Is cassandra incompatible with java 7 version, or with the 64 bit version, or both ? </p> http://www.datastax.com/support-forums/topic/datastax-community-windows-installer-eclipse#post-1209 Wed, 22 Feb 2012 18:42:20 +0000 nickmbailey 1209@http://www.datastax.com/support-forums/ <p>Arodime,</p> <p>Thanks for the bug report. Glad to hear you found a solution. I filed a bug to make sure we don't override locally installed versions of java.</p> <p>Nick </p> http://www.datastax.com/support-forums/topic/datastax-community-windows-installer-eclipse#post-1201 Wed, 22 Feb 2012 13:52:47 +0000 Anonymous 1201@http://www.datastax.com/support-forums/ <p>If it can help:</p> <p>path: "C:\Program Files (x86)\DataStax Community\jre\bin;C:\Program Files (x86)\DataStax Community\python\; [...] ;C:\Program Files (x86)\Java\jre6\bin;"</p> <p>I solve it by putting at "C:\Program Files (x86)\Java\jre6\bin;" at the start of the path variable.</p> <p>path: "C:\Program Files (x86)\Java\jre6\bin;C:\Program Files (x86)\DataStax Community\jre\bin;C:\Program Files (x86)\DataStax Community\python\; [...] ;" </p> http://www.datastax.com/support-forums/topic/datastax-community-windows-installer-eclipse#post-1200 Wed, 22 Feb 2012 13:31:32 +0000 Anonymous 1200@http://www.datastax.com/support-forums/ <p>Hi I installed DataStax Community for Windows this morning on my developer environment and now I can't launch my Eclipse anymore...</p> <p>I get the following error : "Failed to load JNI shared library "C:\Program Files (x86)\DataStax Community\jre\bin\server\jvm.dll"</p> <p>It looks like the jre installed for my server hide (or erased) my previously installed jre version.
