OSX IntelliJ or Eclipse says it needs Java 6

1) Download  Java 6 2014 from Apple:
http://support.apple.com/kb/DL1572

2) Install Oracle JDK 7
http://www.oracle.com/technetwork/java/javase/downloads/index.html

Troubleshooting
Missing libserver.dylib?. If you follow the above instructions you should not have this problem.



Other:
Installing Oracle JDK 7 by itself is almost good but not good enough for Apple OSX. Most apps do not complain.

To get Hadoop 2.+ working on OSX, not using brew, just a pure installation from Hadoop homepage follow this tutorial:

• http://www.michael-noll.com/tutorials/running-hadoop-on-ubuntu-linux-single-node-cluster/
