I just noticed that HADOOP-7484 and MAPREDUCE-3500 recently got committed to trunk and 0.23. I missed them before they were committed. I am curious if we are dropping support for running Hadoop in mixed mode environments? Meaning I want Hadoop to run as 32-bit by default, because that is faster then 64-bit, but if one of my users wants to launch a mapper or reducer in a 64-bit JVM to have access to more memory they can, and the native libraries should be able to work with them.
