HELP - Error on migrate from 0.8 to 0.9 following the procedures
outlined in the Wiki. This is at the mergesegs step, crawldb convert
went fine - trying to deal with segments now as I'm on a slow connection
and would be painful to re-crawl. Anyone seen this or have any ideas on
how to get past this..?? Nutch on fedora, using Java 1.5 Initial
crawls on .9 seem to work just fine but I haven't tried a mergesegs on
the .9 fetched segments yet....
Also this one -2006-12-15 00:28:22,061 WARN util.NativeCodeLoader -
Unable to load native-hadoop library for your platform... using
builtin-java classes where applicable.
I can see how to build native library from Hadoop source but where does
it go in Nutch world - we've only got the Hadoop.jar in lib..?? Does
the native library bring any performance boost to the table..??
