Question

我尝试将我的Play框架（2.4.2）Web应用程序连接到cloudera hbase集群。我在bulid.sbt文件中包含了hbase依赖项，并使用hbase示例代码将单元格插入到表中。但是，我得到了这个异常，这似乎是play框架和Hbase之间的依赖冲突。我还附上了我的示例代码和build.sbt文件。我很感激你的帮助来解决这个错误。

Answer 1

正如我所看到的，问题在于依赖性特别是guava库（这是hadoop的常见问题）我可以看到Play使用较新版本的guava。它没有StopWatch所需的hbase类。

你可以通过多种方式解决这个问题（我知道所有这些都是＆＃39; hacky＆＃39;很遗憾）。

简单的方法是使用像zipkin这样的黑客。我们自己添加StopWatch的地方。

另一种方法是以某种方式分离HBase操作。（这将需要大量的工作和设计变更）

如果sbt支持＆＃39; shading＆＃39;会更容易。我知道它还没有。
您仍然可以使用sbt解决问题，并尝试spark处理类似问题的方法。

Answer 2

我有类似的问题。我在一个项目中有spring，hadoop和hbase。我能够通过在我的pom.xml中明确添加guava lib来解决这个问题。版本必须小于17（我使用的是16.0.1）
