hadoop - Apache 纳奇 2.3 : throwing Error Failed with exit value 255

Question

我使用的是 apache nutch 2.3 版本。我的hadoop版本是2.6.0。Hadoop在单节点上运行。

当我按照nutch的命令运行时

./crawl --index ~/test/seed ~/test -1

上述命令的输出如下。

nutch 有什么问题？我需要安装 Apache Gora 吗？

问题在这里:org.apache.hadoop.mapreduce.lib.input.InvalidInputException: Input path does not exist: file:/usr/local/nutch/runtime/local/bin/--index

Nutch 尝试读取种子文件，但不能。请确保您的命令正确。

希望对您有所帮助，
