I am following MapR Advance installation guide and according to prepare node , i am installing Java (Oracle JDK 6) .
But after MapR installation completes , i see that some node have Open JDK 7 .
Why MapR package install other version of Java if system alreay has java.
This is leading to heterogeneous Java environment in a cluster which may cause problems.
