我试图运行一个简单的mapreduce进程来编写hfiles，以便以后导入hbase表。
提交作业时：

hbase com.pcoa.Driver /test /bulk pcoa

我得到以下异常，表明netty-3.6.6.final.jar在hdfs中不存在（但在这里确实存在）。

-rw-r--r--+ 1 mbeening flprod 1206119 Sep 18 18:25 /dedge1/hadoop/hbase-0.96.1.1-hadoop2/lib/netty-3.6.6.Final.jar

恐怕我不明白如何处理这个配置（？）错误。
有人能给我提些建议吗？
例外情况如下：

Exception in thread "main" java.io.FileNotFoundException: File does not exist:     hdfs://localhost/dedge1/hadoop/hbase-0.96.1.1-hadoop2/lib/netty-3.6.6.Final.jar

以下是我的驾驶程序：

public class Driver {

public static void main(String[] args) throws Exception {

    Configuration conf = new Configuration();
    Job job = new Job(conf, "HBase Bulk Import");

    job.setJarByClass(HBaseKVMapper.class);
    job.setMapperClass(HBaseKVMapper.class);
    job.setMapOutputKeyClass(ImmutableBytesWritable.class);
    job.setMapOutputValueClass(KeyValue.class);

    job.setInputFormatClass(TextInputFormat.class);

    HTable hTable = new HTable(conf, args[2]);
    HFileOutputFormat.configureIncrementalLoad(job, hTable);

    FileInputFormat.addInputPath(job, new Path(args[0]));
    FileOutputFormat.setOutputPath(job, new Path(args[1]));

    job.waitForCompletion(true);
}
}
