Hi List,
Trying to run custom analizer classes I'm always getting
InstantiationException, at first I suspected my own code, but trying with what
is supposed to be the default value
'org.apache.lucene.analysis.standard.StandardAnalyzer' I still get the same
exception.
This is the command
bin/mahout seq2sparse -i /htmless_articles_seq -o /htmless_articles_vectors_1
-ng 3 -x35 -wt tfidf -a org.apache.lucene.analysis.standard.StandardAnalyzer
-nv
Looking a little deeper (ie catching the InstantiationException and throwing
getCause()) InstantiationException in turns out the problem is caused by a
NullPointerException
Exception in thread "main" java.lang.NullPointerException

Am I missing something, is there another way to create/use custom analyzers in
seq2sparse?
