mapred.LocalJobRunner

[Höchstötter Nadine <Ho...@huberverlag.de>]

Hi,
I did a fetch with 2000 Urls on the Url seed list with 1000 threads and 100 urls from one single host.
The fetching process was super quick (60-70 Urls/s), but in between there are always INFO messages from mapred.LocalJobRunner. During the parsing process  the number of those messages increased.
I see something like
009-01-28 17:02:21,886 INFO  mapred.LocalJobRunner - file:/.../segments/20090128132015/content/part-00000/data:67108864+33554432

These messages appear since an hour and then from time to time a messages that another url has been parsed. But I would say that 90% of all output comes from loacaljobrunner.
I think these mapred processes slow down my complete generate/fetch/parse cycle.
What can I do? Is this a normal behavior? Any ideas? What did I wrong?
We are running two Nutch instances on a single machine.
Thanks in advance,
Nadine.
