Hi guys,
I am running in some nightmares when trying to iterate over values in the
Nutch 0.8.2 crawldb. I am getting some hadoop exception such as the
following:
07/01/23 18:33:56 INFO conf.Configuration: parsing
jar:file:/C:/nutch-0.8.2-dev/lib/hadoop-0.4.0-patched.jar!/hadoop-default.xm
l
07/01/23 18:33:56 INFO conf.Configuration: parsing
jar:file:/C:/nutch-0.8.2-dev/nutch-0.8.2-dev.jar!/nutch-default.xml
07/01/23 18:33:56 INFO conf.Configuration: parsing
jar:file:/C:/nutch-0.8.2-dev/nutch-0.8.2-dev.jar!/nutch-site.xml
Exception in thread "main" java.lang.ArithmeticException: / by zero
at
org.apache.hadoop.mapred.lib.HashPartitioner.getPartition(HashPartitioner.ja
va:33)
at
org.apache.hadoop.mapred.MapFileOutputFormat.getEntry(MapFileOutputFormat.ja
va:88)
at org.apache.nutch.crawl.CrawlDbReader.get(CrawlDbReader.java:321)
therefore, if I can iterate over the values contained in the crawldb using
Nutch 0.7 API, I should think this will fix the issue. So the question is;
is Nutch 0.8 backward compatible with Nutch 0.7.2
Thanks,
Armel
