我试图将mahout集成到solr中(使用updaterequestprocessor链),但是每当我尝试初始化classifiercontext时,就会出现以下错误。
信息:模型路径:/home/bayes模型

我的代码如下:params=solrparams.tosolrparams((namedlist)args);
BayesParameters p = new BayesParameters();
String modelPath = params.get("model");
File file=new File(modelPath);
p.set("basePath",file.getAbsolutePath());
LOG.info("model path :"+file.getAbsolutePath());
p.set("classifierType","bayes");
p.set("dataSource","hdfs");
Datastore ds = new InMemoryBayesDatastore(p);
Algorithm alg = new BayesAlgorithm();
ctx = new ClassifierContext(alg,ds);
ctx.initialize();
原因是什么?
