Hi All,
I was trying to run the seq2sparse example of Mahout but every time I get same
error of ClassNotFound Exception. I have seen many people post on the same
issue. Is this a specific problem with this example.
I have checked by printing the classpath from mahout script. Classpath contains
all the jars present in $MAHOUT_HOME/lib which has lucene-core-3.6.0.jar in it.
I have also checked that Analyzer class is present in lucene jar.
Command : $MAHOUT_HOME/bin/mahout seq2sparse -i /clustering/reuters-seqfiles -o
/clustering/reuters-vectors -ow
Error:
Error: java.lang.ClassNotFoundException: org.apache.lucene.analysis.Analyzer
