I'm trying to work out the same thing, to no avail. Would anybody be able to
detail how to add Nutch's Analyzer to the Luke's classpath?
What I'm doing at the moment is:
java -classpath lukeall-0.8.1.jar:/path/to/nutchAnalyzer.jar
org.getopt.luke.Luke
Well ... It could be done, but not easily.
First, NutchDocumentAnalyzer is dependent on other Nutch classes (so you
need nutch-${version}.jar) but they in turn depend on Hadoop (so you
need hadoop-core*.jar), which in turn depends on a dozen or so other
jars ... All of this needs to be added to classpath.
Second, this analyzer doesn't have a no-args constructor, it needs a
Hadoop Configuration argument. Luke can handle only no-args or single
String arg constructors. I would have to change the way Analyzers are
instantiated in Luke so that you can pass an existing instance (e.g. one
that you created in the scripting plugin context).
Third, NutchDocumentAnalyzer uses CommonGrams, which in turn _require_
the presence of a common-grams.utf8 resource on the classpath.
To summarize: unless you want to get your hands dirty with Luke
internals it can't be done.
