Subject Mixed Mode Environments
Date Thu, 02 Feb 2012 16:15:58 GMT
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.
