Question

当我执行nutch命令来创建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.hadoop.util.ToolRunner.run(ToolRunner.java:65)
        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 setup 2.774。

我没有安装hadoop，只有在nutch安装中的hadoop libary因此不是分布式但是本地的nutch设置。

有什么想法吗？提前谢谢！

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

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

Nutch：org.apache.hadoop.mapreduce.lib.input.InvalidInputException：输入路径不存在
