hadoop - Windows 中的 Nutch 1.14 给出异常 java.lang.UnsatisfiedLinkError : org. apache.hadoop.io.nativeio.NativeIO$Windows.access0(Ljava/lang/String;I)Z

Question

While I am running Apache Nutch 1.14 I am getting following exception.

Injector: starting at 2018-07-08 10:15:56
Injector: crawlDb: crawl/crawldb
Injector: urlDir: urls
Injector: Converting injected urls to crawl db entries.
Exception in thread "main" java.lang.UnsatisfiedLinkError: org.apache.hadoop.io.nativeio.NativeIO$Windows.access0(Ljava/lang/String;I)Z
        at org.apache.hadoop.io.nativeio.NativeIO$Windows.access0(Native Method)
        at org.apache.hadoop.io.nativeio.NativeIO$Windows.access(NativeIO.java:609)
        at org.apache.hadoop.fs.FileUtil.canRead(FileUtil.java:977)
        at org.apache.hadoop.util.DiskChecker.checkAccessByFileMethods(DiskChecker.java:187)

我已经安装了 Java 并将 hadoop native 库(即 winutils.exe)放在 c:\winutil\bin 中并指向 HADOOP_HOME。

不确定如何解决它，也找不到任何文档如何在 Windows 中运行 Nutch 1.14。如果有人有解决方案，请告诉我。

Answer 1

我发现解决该错误的唯一方法是来自此线程:
Nutch on windows: ERROR crawl.Injector

关键是注释掉下面这行:

JAVA_LIBRARY_PATH="`cygpath -p -w "$JAVA_LIBRARY_PATH"`"

阅读 $NUTCH_HOME/lib/native 下的 README.txt 以获取有关 JAVA_LIBRARY_PATH 所引用的 hadoop 二进制文件的更多信息。
