Running on multiple CPU's

[Eelco Lempsink]

Hi,

Inspired by http://www.mail-archive.com/[EMAIL PROTECTED]/ msg02394.html I'm trying to run Hadoop on multiple CPU's, but without using HDFS.

mapred.job.tracker = localhost:50099
mapred.map.tasks = 3
mapred.reduce.tasks = 3
mapred.tasktracker.dns.interface = lo

I start the jobtracker and the tasktracker with bin/start-mapred.sh

But, when I'm trying to use this configuration, it hangs after starting:

$ bin/hadoop jar hadoop-0.12.3-examples.jar wordcount conf/ /tmp/wc

07/04/16 15:36:07 INFO mapred.JobClient: Running job: job_0001
07/04/16 15:36:08 INFO mapred.JobClient:  map 0% reduce 0%

In my hadoop-site.xml I have the following options (in XML-format of course): 07/04/16 15:36:06 INFO mapred.InputFormatBase: Total input paths to process : 10 If I'm patient, I might see "Task failed to report status for 601 seconds. Killing." entries appear in my logs, but nothing further (interesting) is happening. I'm a bit puzzled and can't seem to find any good resources about this (kind of) issue. Hopefully someone here can help me out? Thanks in advance!
