Well, many HBase internal limits are based on the architecture so that should impact you right away in resource utilization in the RSs, so a heap or a setting that worked fine for your 32-bit RSs might need to be tuned for a 64-bit environment. Probably might be easier to run a 32-bit JVM in the 64-bit boxes and phase out the old 32-bit nodes after you test for a while in a couple of the 64-bit nodes new settings.
