> Allow numactl constraints to be applied to the datanode process. The implementation I
have in mind involves two environment variables (enable and parameters) in the datanode startup
process. Basically, if enabled and numactl exists on the system, then start the java process
using it. Provide a default set of parameters, and allow the user to override the default.
Wiring this up for the non-jsvc use case seems straightforward. Not sure how this can be supported
using jsvc.
