Do you have running task trackers and data nodes? Which Nutch job did you start? Any custom code?

Check the logs of of the four Hadoop daemons, there may be something there.

Hi all,

If this is definitely a Hadoop issue, as opposed to it being an issue
caused by Nutch, I'll happily go ask on the Hadoop mailing list...

Anyway, I'm kicking off a nutch ibject job via Hadoop 0.20.2 with Nutch 1.4.
(I'm using v 0.20.2 because this is the library version included with
Nutch 1.4.)

This is the output:

2012-05-01 16:11:06,869 INFO org.apache.hadoop.mapred.JobTracker:
Initializing job_201205011600_0001

2012-05-01 16:11:07,102 INFO org.apache.hadoop.mapred.JobInProgress:
tip:task_201205011600_0001_m_000000 has split on
node:/default-rack/localhost


It then does nothing else. The Hadoop job tracker says Total
Submissions = 1, yet states that there are/have been, no running,
completed or failed jobs.


Any ideas as to what's stalling?

Cheers,
