Question

我收到像kkslct到达此处的错误： http://eldadlevy.wordpress.com/2011/02/05/hadoop-binary-files-processing-entroduced-by-image-duplicates-finder/ kkslct解决了它，但我做不到。有什么想法吗？

代码是：

public class BinaryFilesToHadoopSequenceFileMapper extends Mapper<Object, Text, Text, BytesWritable> {

public void map(Object key, Text value, Context context) 
throws IOException, InterruptedException {


    String uri = value.toString();
    Configuration conf = new Configuration();
    FSDataInputStream in = null;
    try {
        FileSystem fs = FileSystem.get(URI.create(uri), conf); ERROR HERE

我得到的错误如下： ERROR BinaryFilesToHadoopSequenceFileMapper错误，uri：L 2 ;fR ӐT ％2 PHe Z әh T ��z�/�#��:� null class java.lang.IllegalArgumentException with Cause: java.net.URISyntaxException: Illegal character in path at index 13: L��2��;fR��ӐT�%2��PHe�Z�әh��T�� z / ＃：

这浪费了半天时间。我忘记了：输入是一个文件，包含所有图像文件作为HDFS文件名。例如：

HDFS：//本地主机：8022 /用户/ elevy / smallArchiveImages / WonderWoman.jpg
