File be/src/util/cpu-info.cc:

PS5, Line 161: getcpu
> should that say sched_getcpu()?
Yes - sched_getcpu() is a glibc wrapper around the getcpu() syscall.


Line 186:     LOG(FATAL) << "Could not find nodes in /sys/devices/system/node";
> are we confident that all distros impala runs on will have this?
Oops, I intended to check for the existence of the directory (it's not present 
if the kernel has NUMA support disabled). Now all errors should be non-fatal 
and just fall back to assuming one node.
