> SegmentMerger and SegmentReader should use NutchJob

> Key: NUTCH-333
> URL: https://issues.apache.org/jira/browse/NUTCH-333
> Project: Nutch
> Issue Type: Bug
> Affects Versions: 0.9.0
> Reporter: [EMAIL PROTECTED]
> Priority: Minor
> Attachments: nutch333.patch, use-nutch-job_patch.txt
>
>
> I have a job jar that is nutch with additions. I can launch this job jar on a
> pure hadoop platform usually without issue. I can run nutch jobs -- update
> db, invert links, etc. -- without issue. Recently I tried to do the same
> with SegmentMerg'ing only it would fail complaining about ClassNotFound:
> 2006-07-28 20:43:54,371 WARN org.apache.hadoop.mapred.JobTracker: job init
> failed
> java.io.IOException: java.lang.ClassNotFoundException:
> org.apache.nutch.segment.SegmentMerger$ObjectInputFormat
> at
> org.apache.hadoop.mapred.JobInProgress.initTasks(JobInProgress.java:130)
> at
> org.apache.hadoop.mapred.JobTracker$JobInitThread.run(JobTracker.java:310)
> at java.lang.Thread.run(Thread.java:595)
> java.io.IOException: Job failed!
> After digging and chatting today with Stefan, the SegmentMerger and
> SegmentReader classes are not like the others. Others make a new JobConf
> inside in their job setup by doing a 'new NutchJob' whereas Segment* does
> 'new JobConf'. Sure enough, if I make the change, all works.
> NutchJob triggers the setting of the job jar into the configuration
> (JobConf.findContainingJar is run). This doesn't happen for 'new JobConf'.
