Re: Problem with merge-output
Hi,
I am also facing this same problem. Have you figured out a solution to this
yet?
Also i keep getting the following error every time i recrawl -
DeleteDuplicates: java.io.IOException: Job failed!
at org.apache.hadoop.mapred.JobClient.runJob(JobClient.java:604)
at org.apache.nutch.indexer.DeleteDuplicates.dedup(DeleteDuplicates.java
:491)
at org.apache.nutch.indexer.DeleteDuplicates.run(DeleteDuplicates.java:515)
at org.apache.hadoop.util.ToolBase.doMain(ToolBase.java:189)
at org.apache.nutch.indexer.DeleteDuplicates.main(DeleteDuplicates.java:499)
Can anyone please help me out with these problems?
Thanks,
-Chris

Re: Problem with merge-output
Posted by chris sleeman <ch...@gmail.com>.
My apologies..The dedup error was "mea culpa".... I was using an older
version of the lucene jar..
However, I still am getting the -
"IndexMerger: java.io.IOException: Target crawl-test/index/merge-output
already exists" exception.
Once a crawl is completed successfully, can I simply delete the merge-output
dir for my next crawl, or is merge-output used elsewhere?
Regards,
Chris
