Question

我尝试按照the official documentation安装和运行OpenTSDB，我使用sudo ./build/tsdb tsd --port=4242 --config=/path/to/opentsdb/src/opentsdb.conf --staticroot=build/staticroot --cachedir="$tsdtmp"启动OpenTSDB，但是一切正常，但是当我尝试使用./tsdb mkmetric mysql.bytes_received mysql.bytes_sent创建指标时，却显示错误下面。任何想法有什么问题，我该如何解决？如果需要任何其他信息，请告诉我。预先感谢。

Answer 1

NoClassDefFoundError-在jvm试图加载类时出现，但找不到该类。或尝试初始化不兼容的版本。我建议您更改库，如果有帮助的话。

Answer 2

根据正在执行的操作的完整上下文，您可以在各种与HBase相关的软件包中找到该类。在我的上下文中，最明显的选择是hbase-client-x.x.x.jar（x.x.x是适合您的HBase版本）。

您可以在此处查看所有内容，选择适合您的版本，并相应地下载或更新pom.xml： https://mvnrepository.com/artifact/org.apache.hbase/hbase-client

如果这个罐子不适合您，那么在其他几个罐子里也可以找到chis类。

如果使用Eclipse，则有一个方便的工具可让您查看哪些jars包含所需的类，并通过这种方式可以看到在您所做的工作中最有意义的东西。在Mac下，您可以按CMD+Shift+T并输入班级名称。

希望这会有所帮助。
