问题
I am trying to run Apache Nutch 1.15 (local) on Windows 10, I have followed the same steps as mentioned on https://wiki.apache.org/nutch/NutchTutorial and https://wiki.apache.org/nutch/NutchHadoopSingleNodeTutorial. When I try to inject the urls using this command on cygwin : bin/nutch inject crawl/crawldb urls i get this error:
Injector: java.io.IOException: (null) entry in command string: null chmod
0644 C:\Users\INFO\Desktop\apache-nutch1.15\runtime\local\crawl\crawldb\.locked
when put %HADOOP_HOME% on system path (solution proposed on Apache Nutch error: Injector: java.io.IOException: (null) entry in command string: null chmod 0644)
i get a new error :
Exception in thread "main" java.lang.UnsatisfiedLinkError: org.apache.hadoop.io.nativeio.NativeIO$Windows.access0(Ljava/lang/String;I)Z
by the way as HADOOP_HOME i've tried both hadoop-2.8.0 and winutil folder but same problem.
please help.
