Phew,... The fix for this was a DUD.
In Lucene 4.2.1 the package name for this class was changed to org.apache.lucene.analysis.en.EnglishAnalyzer. Notice 'en' in the package path. This should work. ________________________________ From: Chris Harrington <ch...@heystaks.com> To: user@mahout.apache.org Sent: Monday, April 22, 2013 6:08 AM Subject: seq2sparse in 0.8 throwing class not found for analyzers HI all, I'm trying to run the seq2sparse tool with one of the lucene analyzers but it throws a class not found exception mahout seq2sparse -i ./contentDataDir/sequenced -o ./contentDataDir/sparseVectors --namedVector -wt tf -a org.apache.lucene.analysis.EnglishAnalyzer java.lang.ClassNotFoundException: org.apache.lucene.analysis.EnglishAnalyzer Looking at the output from bin/mahout classpath it shows that lucene-analyzers-common-4.2.1.jar is in there as a dependancy so any idea why is the above throwing an exception.
