Thanks, Håvard (and Doug, in the original email). Those pointers, plus a few other tips from elsewhere, did the trick. I'm now up and running with all CPUs.
One thing I found along the way was that if I did not set mapred.child.heap.size, I would run out of heap space in initialization of inject with even a small URL list. Is this normal? If so, why not have a reasonable default for heap.size? If this is not normal, is it indicative of something else I might have misconfigured? In any case, I'm running now, just curious (and would like for others to avoid having to "discover" this). -Doug -- View this message in context: http://www.nabble.com/Best-performance-approach-for-single-MP-machine--tf1970539.html#a5430453 Sent from the Nutch - User forum at Nabble.com.
