java Nutch爬网错误输入路径不存在

我有带有2个datanode服务器的nutch/hadoop。我尝试爬网一些URL，但nutch失败，出现以下错误：

Fetcher: segment: crawl/segments
Fetcher: org.apache.hadoop.mapred.InvalidInputException: Input path does not exist: hdfs://devcluster01:9000/user/nutch/crawl/segments/crawl_generate

    at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:65)
    at org.apache.nutch.fetcher.Fetcher.main(Fetcher.java:1116)

有人能帮我吗？我不知道怎么解决这个问题！很多很多Thx
