Question

我必须使用Nutch 2.3.1设置hadoop堆栈。支持的hbase for hadoop 2.7.4版本是1.2.6，我已成功配置和测试。但是当我编译Nutch时，我得到了跟踪并抓取了一个示例页面，我收到了这个错误。

根据我的搜索，例如this和this，可以为Nutch 2.3.1编译Hbase 1.x.但如何编译我不知道。有人可以指导（步骤等）

Apache Gora 0.7支持HBase 1.2.3（+）：https://issues.apache.org/jira/browse/GORA-443

你可以看看https://stackoverflow.com/a/39837926/582789我写的如何修改Nutch 2.3.1以使用Apache Gora 0.7。关于该答案中的补丁https://paste.apache.org/jjqz，请使用＆＃34; 0.7＆＃34;它显示＆＃34; 0.7-SNAPSHOT＆＃34;。

顺便说一下，Apache Gora 0.8昨天发布了:)只需将0.8改为0.8即可。
