java - Nutch Crawl 错误 - 输入路径不存在

Question

我有带 2 个数据节点服务器的 nutch/hadoop。我尝试抓取一些网址，但 nutch 失败并出现此错误:

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)

有人可以帮助我吗？我不知道如何解决这个问题!非常感谢!

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

路径错误或解析阶段未完成。
