Subject Re: Running JobTracker on a separate machine
Date Tue, 22 Mar 2011 04:36:19 GMT
start-all.sh will attempt to launch a JobTracker on the same machine
it was executed on (which would fail since mapred.job.tracker would
point to an unavailable binding address). The right way is to launch
these individually (or perhaps writing a custom/modified script to do
what you need).
