Hi,
I'd like to add a new stage called "updatescore" after "updatedb" to
Nutch 2.1.
I tried two ways for this:
1) public class ScoreUpdaterJob extends NutchTool implements Tool;
Nutch requires me to define the InputFormat, OutputFormat etc. to
perform Map-reduce calculations.
I don't want to perform map-reduce but call a Giraph job to run on
Hadoop. When it's finished, Nutch can go on its way.
2) public class ScoreUpdaterJob implements Tool;
or public class ScoreUpdaterJob;
Then I can't use setJarClass of NutchTool, so hadoop job fails:
Caused by: java.lang.ClassNotFoundException:
org.apache.giraph.examples.LinkRank.LinkRankComputation
How can I fix this? What's the best way to add a giraph job as a Nutch
stage?
Thanks,
