Spark使用HanLP分词

  1. 将HanLP的data(包含词典和模型)放到hdfs上，然后在项目配置文件hanlp.properties中配置root的路径，比如：root=hdfs://localhost:9000/tmp/
  2. 实现com.hankcs.hanlp.corpus.io.IIOAdapter接口
public static class HadoopFileIoAdapter implements IIOAdapter {

        @Override
        public InputStream open(String path) throws IOException {
            Configuration conf = new Configuration();
            FileSystem fs = FileSystem.get(URI.create(path), conf);
            return fs.open(new Path(path));
        }

        @Override
        public OutputStream create(String path) throws IOException {
            Configuration conf = new Configuration();
            FileSystem fs = FileSystem.get(URI.create(path), conf);
            OutputStream out = fs.create(new Path(path));
            return out;
        }
    }
  1. 设置IoAdapter，创建分词器
private static Segment segment;

static {
    HanLP.Config.IOAdapter = new HadoopFileIoAdapter();
    segment = new CRFSegment();
}

然后，就可以在Spark的操作中使用segment进行分词了。
