---------------------------------
bq. Yep, the wiki is here: http://wiki.apache.org/hadoop/HowToUseJCarder
Thanks. I was hoping for a simpler process/script to reproduce these graphs
though :) I agree with you on the wiki that it's important to avoid false
positives to reduce noise. These two cycles are already borderline and
practically harmless, as unlike start/stop, init/shutdown doesn't overlap
registration.
bq. I'm working on getting access to the new build infrastructure so I can set
up hudson jobs to run jcarder on a regular basis
This will be a time saver. +1 and Thanks!
