Arun C Murthy commented on MAPREDUCE-4334:
------------------------------------------
bq. How is it onerous? Packages could easily do this as part of the install on
platforms where it's supported.
This doesn't make sense. What if CPU isolation is disabled? Do you still want
'packages' to make it part of the install?
Clearly, we need to support taskset for platforms on which cgroups isn't
supported e.g. RHEL5. For taskset you need super-user privs - would you prefer
packages to do it too?
Yes, LTC is a pain, but using it consistently (e.g. for both cgroups and
taskset) seems better than having multiple steps forced on the admin (LCE +
cgroups + taskset etc.).
