java - Nutch抓取错误-输入路径不存在

我有2个datanode服务器的坚果/鹰嘴 bean 。我尝试抓取一些网址，但出现以下错误时，nutch失败:

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？我不知道该怎么解决!
很多很多!

最佳答案

验证nutct / crawl / segments / crawl_generate路径是否正确。

路径错误或解析阶段未完成。
