我已将 hbase-client-jar 、hbase-common-jar 、metric-core-jar 添加到我的 eclipse POM 文件中...我无法找到我必须做的更改...请帮助我解决这个问题..

【问题讨论】：

java.lang.NoClassDefFoundError: com/yammer/metrics/core/Gauge 寻找合适的依赖及其包装
我在我的eclipse中添加了metric-core-jar
在 maven eclipse 中构建给出错误...在创建阴影 jar 时应该存在于 maven 依赖项中
@s.s 请在您的代码中更改 core-site.xml 我可以看到中间有一些空格。此外，请在代码中提供 zookeeper 属性。阅读此github issues
谢谢 jose ..抱歉中间的空格不在代码中..它只在这里..你能告诉如何设置“zookeeper.znode.parent”吗？

【解决方案1】：

我解决了这个问题，因为 Caused by: java.lang.NoClassDefFoundError: com/yammer/metrics/core/Gauge 中存在问题因此，将 metrics-core-2.2.0.jar 添加到 HADOOP_CLASSPATH 不起作用...所以我将此 jar 添加到 HADOOP mapred/lib、hdfs/lib、common/lib 文件夹中...因此此 jar 在类路径中可用 ..
