当我执行 nutch 命令创建 crawldb 文件夹和内容时：

soporte@CNEOSYLAP /usr/local/apache-nutch-2.2.1/runtime/local
$ bin/nutch crawl urls -dir crawl -depth 3 -topN 5

我收到此错误：

InjectorJob: Using class org.apache.gora.hbase.store.HBaseStore as the Gora storage class.
Exception in thread "main" org.apache.hadoop.mapreduce.lib.input.InvalidInputException: Input path does not exist: file:/C:/cygwin/usr/local/apache-nutch-2.2.1/runtime/local/crawl

        at org.apache.nutch.crawl.Crawler.main(Crawler.java:257)

我正在使用 apache-nutch-2.2.1、hadoop-0.20.2-core.jar、hbase-0.90.4.jar 和 CygWin 设置 2.774。

我没有安装 hadoop，只有 nutch 安装中的 hadoop 库，因此不是分布式而是本地 nutch 设置。

任何想法？提前致谢！

编辑：

手动创建目录时，我收到另一个错误：

soporte@CNEOSYLAP /usr/local/apache-nutch-2.2.1/runtime/local
$ mkdir crawl

soporte@CNEOSYLAP /usr/local/apache-nutch-2.2.1/runtime/local
$ chmod 777 crawl

soporte@CNEOSYLAP /usr/local/apache-nutch-2.2.1/runtime/local
$ bin/nutch crawl urls -dir crawl -depth 3 -topN 5
cygpath: can't convert empty path

如果要使用-dir crawl，首先需要创建文件夹file:/C:/cygwin/usr/local/apache-nutch-2.2.1/runtime/local/crawl。
