无法在 Eclipse 中使用 java 访问 hbase
Not able to access hbase with java in eclipse
我是 hadoop 和 hbase 的新手，并创建了一些小程序来使用 java 在 hbase 中创建 table api.But 我陷入了一个大错误并且无法解决它.

此外，当我在终端中使用 运行 jps 命令时，它显示我的 hmaster 和 hregionserver 是 running.My hbase shell 也 运行ning 很好但是当我尝试运行 该程序向我显示了这一堆错误。
请帮助我在过去 2 天里苦苦挣扎，但是 none 的解决方案帮助我摆脱了困境。
提前致谢
由于现有的修复将此添加为答案而不仅仅是评论：
问题是您的 Yammer 版本与 hbase 不兼容。尝试删除其他所有内容，只使用 hbase。然后慢慢的一次加一个库，直到失败为止。 （或使用第 3 方依赖分析）。
还要确保 yammer 库包含在您的路径中。
我是 hadoop 和 hbase 的新手，并创建了一些小程序来使用 java 在 hbase 中创建 table api.But 我陷入了一个大错误并且无法解决它.
这是我在 Eclipse 运行 中 Java 的程序 Ubuntu

此外，当我在终端中使用 运行 jps 命令时，它显示我的 hmaster 和 hregionserver 是 running.My hbase shell 也 运行ning 很好但是当我尝试运行 该程序向我显示了这一堆错误。 请帮助我在过去 2 天里苦苦挣扎，但是 none 的解决方案帮助我摆脱了困境。 提前致谢
由于现有的修复将此添加为答案而不仅仅是评论：
问题是您的 Yammer 版本与 hbase 不兼容。尝试删除其他所有内容，只使用 hbase。然后慢慢的一次加一个库，直到失败为止。 （或使用第 3 方依赖分析）。
还要确保 yammer 库包含在您的路径中。
