HBase Java API HTrace錯誤

我想創建一個Java API來訪問HBase DB，但我總是面臨着我的項目中的這個錯誤;HBase Java API HTrace錯誤

但我在我的項目加入HTRACE罐子

HBase的版本：1.1.2

的Hadoop版本：2.6.0

您需要添加合適的罐子文件添加到項目中，將htrace-core-3.1.0 jar文件添加到項目類路徑中，然後運行它。
htrace-core

<dependency> 
    <groupId>org.apache.htrace</groupId> 
    <artifactId>htrace-core</artifactId> 
    <version>3.1.0-incubating</version> 
</dependency>
