當我執行Nutch的命令來創建crawldb文件夾和內容：Nutch的：org.apache.hadoop.mapreduce.lib.input.InvalidInputException：輸入路徑不存在
[email protected] /usr/local/apache-nutch-2.2.1/runtime/local
$ bin/nutch crawl urls -dir crawl -depth 3 -topN 5
我得到這個錯誤：
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

我使用apache-nutch-2.2.1，hadoop-0.20.2-core.jar，hbase-0.90.4.jar和CygWin設置2.774。
我沒有安裝hadoop，只有hadoop libary內部安裝，因此不是一個分佈式，但本地nutch設置。
有什麼想法？ 在此先感謝！
編輯：
當手動創建目錄，我得到另一個錯誤：
[email protected] /usr/local/apache-nutch-2.2.1/runtime/local
$ mkdir crawl
[email protected] /usr/local/apache-nutch-2.2.1/runtime/local
$ chmod 777 crawl
[email protected] /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

你有沒有想過這個？ – gsingh2011
這個版本似乎不贊成使用「nutch crawl」命令。請使用「抓取」腳本，例如：「bin/crawl url crawl 1」。 [參考這裏]（http://wiki.apache.org/nutch/NutchTutorial#A3.3._Using_the_crawl_script） –
