Hello Dan Burkert, Internal Jenkins,
I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/1864
to look at the new patch set (#2).
Change subject: KUDU-1290. Fix CHECK failures when some CPUs are disabled
......................................................................
KUDU-1290. Fix CHECK failures when some CPUs are disabled
This adds a new function base::MaxCPUID() which uses
/sys/devices/system/cpu/present to determine which CPUs are present on the
system. This is an alternative to base::NumCPUs() which doesn't count any CPUs
which have been administratively disabled.
The few places where we use CPU ID to index into a collection are changed
to use this new API.
I verified that, if I disabled one of my CPUs, the master crashed a few minutes
after startup without the patch. With the patch, it seems stable.
